[@tedpreston4155]

I've watched several 4L60E disasssembly videos, and yours is by far the best. You and your cameraman deserve kudos for filming things in a way that shows good detail of what you're doing. Starting with clean parts and moving slowly through the process makes a lot of difference to those of us who don't do this every day. Besides being a good mechanic, you're also a good teacher! I think I have the courage to delve into my tranny now! I have little doubt that I'll find a broken sun shell. (no reverse, no second or fourth gear.) Kudos also to your parents and whomever else helped you in your youth to overcome your deformity. I wish my aunt and uncle had done the same. After too much coddling, my cousin doesn't use his "stump" nearly as effortlessly as you appear to do. Thalidomide be damned!

Hey Robert....I'm enjoying your videos on the 4L60. I took an automatic trans class around 20 years ago. I love doing maintenance and repairs on the side for my friends and family as well as the occasional buy and flip. I have an 05 Yukon XL 1500 that rolled in the shop. It's pretty evident to me based off the symptoms that the 3-4 clutch pack is burnt. I look forward to supporting you by buying the products / tools you're recommending. Before I just yank it and rebuild it, I want to make sure there's no other issues to address. What bothers me is that it doesn't shift out of 1st gear on it's own when in drive. If I move the shifter into L2 it will go from 1-2 normally. When I move it to L3 the engine freewheels. The trans had been regularly serviced every 30K. When it failed it was pulling a heavier camper on a long trip. The dash indicated a trans temp warning and that's when this all started. Any help pointing me in the right direction for diagnosis would be appreciated. There are no DTC's currently on the computer.

[@viclopez3365]

Hello Robert, I hope all is well my friend. I don’t expect you to remember me, but this is Vic, I messaged you about a 4l60e father and son project on my son’s 2006 Trailblazer 4.2. I purchased 2 books and watch your videos and I can’t figure out what I did wrong. I I can get the torque converter to spin freely on the input shaft, it binds and only rotates about 2 to 3 inches in both directions (clockwise and counter clockwise). I’ve installed and replaced many transmission in the past and this was never a problem. My question to you is, what could’ve I donee wrong to cause the converter binding. I’m so embarrassed and defeated by this build and I feel like I let my son down. Any help you can provide will be greatly appreciated. Please let me know what I need to double check to make this right. Thanks Robert, have an awesome evening my friend

[@SouthpawAutoworks]

Hi Vic, This rings a bell (father son project). That's awesome, BTW. Bummer about the setback. I can totally relate... Can you share more about the problem? Is the trans still on the bench, or installed in the vehicle? Are you using a new converter? Reusing the old converter? Were any of the pump components replaced? (new pump cover, new pump body, etc) When overhauling the pump, after you reassembled it did you verify that the pump internals were free to rotate? If so, what method did you use to verify this?

Will a 97 s10 blazer tranny work on a 95 suburban? Both 4x4

[@SouthpawAutoworks]

Unfortunately, the '95 4L60E is a standalone year. In other words, it doesn't interchange with any other years of 4L60E. The wiring harness, among other things, are different than earlier/later versions. On a positive note, parts can be swapped, in order to make another year 4L60E work in a '95 application. There are different sized bell housings (and bell housings designs), depending on year/engine size/etc. Also different torque converters, pumps, etc. I'd like to put together a video on each of these subjects, when time permits.

My 4L65e has a pressed on Rear Ring Gear onto the 4Wheel Drive Tail Shaft. I successfully pressed it off, but now trying to get the 2 Wheel Drive Tail Shaft pressed into the Rear Ring Gear is a real problem. Because the tail shaft has the speedometer gear, it is larger than than the opening of the case. So I guess I have to make a jig to hold the case and ring gear while I press in the tail shaft. What a pain! Thanks for your informative videos.

[@SouthpawAutoworks]

If the ring gear has the dimples, then getting the shaft back through the ring gear will require a little persuasion. If it were me... (disclaimer: do what I do at your own risk) I'd stack in the rear guts, all the way up to the Center Support (install rear ring gear, rear planet, etc, etc, and ultimately install center support). Install the large yellow snap ring, that retains the Center Support inside of the trans case. Now, the Center Support provides a surface to work against. Gently install the output shaft, lining up the splines. When I encounter the press-fit, I use the bottom of my hammer handle (rubber coated), and strike the rear of the output shaft. Shouldn't take much effort to install it. Hope this helps.

[@michaelbaskinmichael9862]

Is it possible to just put in rental lt input drum and new band get out without disturbing to much

[@michaelbaskinmichael9862]

Input drum

[@SouthpawAutoworks]

I believe that you're asking...is it possible to replace a worn out band, and an Input Drum that has worn out clutches, with a new band and a new Input Drum (that already has new clutches installed)? It is possible to do this, and not have to remove everything else from inside the trans. This can even be done without removing the VB (valve-body). However.......... If your trans has a band and some clutches that are smoked, there's a reason that they're smoked. If we simply replace old clutches with new ones, I imagine that it will get the trans/vehicle back on the road. But, it probably won't be long before the new clutches are smoked again (this applies to the band, too). If we want to do the job once, and be done with it, then it's important to identify why the clutches failed in the first place (root cause of failure). Could be caused by a number of things inside the trans, and even outside the trans. A video topic for another time.

[@raymonddevore1934]

My brother bought a trans off a guy for his 94 chevy k1500 4wd..guy said he had rebuilt it. It's the 4L60e Trans. The trans will go in all gears and move in every gear. The problem is in overdrive,3, or 2 it stays in one gear and doesn't shift. If you put trans in low gear it will shift while driving and as soon as you let off the throttle it will down shift really fast....if your going fast enough it will slide the rear tires. Any idea what may be the issue?

[@SouthpawAutoworks]

It sounds like the transmission is in "Limp Mode." If the PCM (computer) detects a transmission problem, it can put the trans into Limp Mode....so the vehicle can be "limped" to a repair shop. When in Limp Mode, the PCM cuts off electrical power to the trans. When the trans has no electricity supplied to it, the trans will default to 3rd gear, with the shifter in OD mode. There's more to it, but I'll spare you the details. Do you have a check engine light? Have you pulled codes?

[@250gtskyline5]

I just noticed the guy only had 1 hand! It’s encouraging because if you have two hands you don’t fix your transmission, you should lean from this guy.

[@SouthpawAutoworks]

I'm on a mission to get more people involved with automatic transmissions. People are intimidated by these things...and I want to change that.

[@csbuckn]

I see you didnt remove the last part(reverse piston?). Is this because they are not removed typically or is it because of the tooling needed or another reason?

[@SouthpawAutoworks]

It's simply due to habit... When I was wrenching for a transmission shop, I would only tear the unit down far enough to look at all of the usual suspects. After the inspection was complete, a parts list was put together. The service-writer would use my parts list to put together an estimate for the customer. The customer would either give us the green light...or look into other options. So, during a teardown, there was no need to remove the Low-Reverse piston....not until I knew that we were moving forward with the rebuild/repair. Removing the piston before then, could potentially result in time wasted...and time is money. To answer your question... For a rebuild, the Low-Reverse piston must be removed. It has three (3) seals on it, that must be replaced. Plus, the piston must be removed in order to clean the piston, and clean the transmission case. For the sake of these videos, I really need to be showing the piston removal, during teardown. Thank you for pointing this out. Much appreciated.

[@gabrielfranjul7171]

Just now got the time and parts to reassemble it, wish me luck One question, the TCC Solenoid used a small check ball? I think one came out of the snout of the tcc@@SouthpawAutoworks

[@SouthpawAutoworks]

If we're talking about a 0.250" check-ball...... That's something that some builders would do on a 700-R4. It's not necessary on the 4L60E. If you don't already know, the 4L60E is the successor to the 700-R4 (also known as the 4L60...no E). The early 4L60E (93-94) uses a nearly identical pump to the 700-R4. The 700-R4 is controlled by a cable (connected to the carburetor) and a governor (driven by wheel speed). This trans lived in the days before computer controls. Even though there was no computer, the trans, however, did still need electricity....in order to operate the TCC solenoid. Under the right conditions, a pressure switch, located on the VB (valve-body), would create a path to ground, for the TCC Solenoid circuit...which would turn on the solenoid...which causes oil to flow in a different direction inside the converter...which causes the TCC to engage. If someone didn't want to run a power wire to the trans, but still wanted the TCC to work, this is where the check-ball located in the snout comes into the picture. It's not perfect (it has a drawback), but it is a solution. If we're talking about a check-ball that's much smaller than 0.250".... It could've been the check-ball located inside of the TCC Solenoid. It's not supposed to come out. If you're interested in learning about how the 4L60E On/Off solenoids work... 4L60E Shift Solenoid - Part 1 (Basic Operation) kzbin.info/www/bejne/fJKmmYqjmNh0nas Note: Both shift solenoids, and the TCC Solenoid, are On/Off solenoids. PWM solenoids are a different animal.

[@gabrielfranjul7171]

Mine its a 94 On/Off the year pre PWM Yea its a smaller check ball like 3/16 I didnt exactly know where it came but asking some people told me that the only place it couldve come off was the TCC, so this means I need a new TCC Solenoid@@SouthpawAutoworks

My new input shaft o-ring has a slight surface tear, should I get a new one or reuse the original that has no tear an looks good an not hard?

[@SouthpawAutoworks]

That is a bummer about the new one. But, good eye!! When little details, like this one, get overlooked, headaches occur. You did good... Ideally, get a new replacement O-ring. If there ends up being a problem with the used O-ring, down the road, it will cause torque converter issues. And replacing an old O-ring, at a later date, will require trans removal. However, if getting a new O-ring is not an option (due to a time constraint), if it were me, I would have to reuse the old one (Pliable with no cuts/tears) over installing a damaged one. There are two(2) different O-ring sizes, depending on which input shaft your 4L60E is equipped with: 298mm converter/shaft VS 300mm converter/shaft. 298mm Shaft: 93-97 300mm Shaft: 98-14 Short Video about your question and 298mm VS 300mm: kzbin.info/www/bejne/aGmahomZrKmaftE 4L60E Input Shaft O-Rings: ***Paid Links*** 298mm: amzn.to/3CmjHsP 300mm: amzn.to/2ZrGFA0 Ebay: ebay.us/h7lpLB DISCLOSURE: 🕵 As an Amazon Associate I earn from qualifying purchases.

Hi, thank you for the informative video... I am busy building my '93 4L60e... Actually, the casting date say 92... Will you post a video where you assemble the Box? If not, When I striped my 3-4 Stack, I found that there were no Load Release Springs in the 4th Gear assembly... Is that okay? My Workshop manual says it has to be there (in all goxes since 1988) I would appreceate if you could help. I am in Germany and it look like the people here have no idea...

[@SouthpawAutoworks]

We plan on doing a complete rebuild series on the 4L60E. However, we're currently busy working on a TH400 video series. TH400 Rebuild Series - Coming Soon kzbin.info/www/bejne/p2HIlJyOip2Me6s To answer your question... I always install them (stock build). I know some builders will throw them out during the rebuild. However, I was trained to use those springs. It's my understanding that those springs are used to help keep the 3-4 Clutch off, when the trans is in 1st and 2nd gear. When the engine revs high enough in 1st or 2nd gear, the Input Drum will also spin fast. The residual oil located in the drum (right near the 3-4 Clutch piston) will grow "taller" (due to centrifugal force) and start to push on the 3-4 Clutch piston. The theory is, the 3-4 Clutch will not fully apply...however, it'll drag a little. This dragging builds heat and burns up the clutch pack, over time. Like I said, some people throw them in the trash...I happen to use them. To each their own.
