You deserve way more views, dude. Thanks for the knowledge!

[@jimhancock7080]

I got a 04 trailblazer that rev an 1 an 2nd it’s seems fine then going to 3rd rpm’s starts maxing out an don’t wanna shift what do I need to do? Thanks y’all!

[@briangarduno2501]

I have the same thing happening on my Silverado would appreciate the help on a possible fix because I recently ls swapped it with a Holley terminator and can’t read codes any gel is appreciated

[@boostedkidproductions9719]

​@@briangarduno2501did you find the problem mine is doing the same thing

[@danjim7056]

From my research (why I'm here) one of the most common issues with 4l60e is loss of 3rd and 4th from the 3-4 clutch pack burning up.

[@boostedkidproductions9719]

@@danjim7056 I'm ordering a remanufactured transmission $2600 with 5 year warranty I think it's cheaper than buying a used car and having to replace parts on it

[@BonezOnDaBeat]

Did you guys ever find out what it was. My 08 Yukon Denali is doing the same thing

[@letstryit6248]

I’ve got a rebuilt 4l60e (10k miles on it and out of warranty). Shifts excellent and firm but intermittently 2-3 flares (mostly when trans is not up to temp). Where should I start with diagnosing the issue?

[@markchapa9989]

Please don't stop making videos on this transmission

[@JimvMAGA]

please help me I have a Silverado 2009 1500 transmission line rotted I fixed that and put new filter in but when I drive it it will move then feels like it goes in neutral with motor racing I let go of gas and will go again can that be the solenoid burned out

[@bobbyrichie3509]

Is it possible for your truck to not throw any codes if yur solenoid is bad

[@sir_charelzwatzbrackin7705]

Awesome sharing!! I have 0742,0785,2761 codes on my 04 Silverado all at once. Any suggestions before I replace the four parts?

[@theldgxc6274]

Maybe you can help have a 1999 silverado. Issue is when first start driving i have to take my foot off the gas for it to go into 2nd but after that shifts in all gears normally. Would that be a shift solenoid issue? Have been told different things by different people. From it being the acceleration pedal switch to solenoid a. Can you guide me toward a fix for it?

[@choppers2yadie]

Did you get this figured out? If so, what was it?

[@Suzpek211]

A little late to the party but where did you get the vac pump 5/8 hose adapter? I can't find one. Did u make it?

[@steadyfishingmiami9677]

I got a p0894 code on a 05 astro van. Car went into gear and then reverse but after i throw it in park thats it wouldnt go in any more. Before the first gear to second shift would shift hard but on high rpms it wouldnt. What do you recommended

[@urboyced26]

Good video my brother! Only thing is…I don’t trust eBay parts at all, I go with Amazon AC Delco parts or Dealer themselves bro, I mean at least when it comes to my Transmission! 👍🏾

[@koraykumru1295]

Does the ranch dressing help the shift from 2nd to 3rd?

[@ScottiesHobbies]

As long as its butter milk ranch. 🤣

[@MJsLandscaping-i9e]

Thanks for the vid. Question. I have an 04 envoy xl. I noticed when key on engine off I heard a rapid clicking sound coming from trans pan. Took the pan off and determined it was coming from a shift solenoid. I unplugged the solenoid connector and the clicking stopped. I switched the shift solenoids around and same thing happened. I'm thinking more along wiring harness being the issue but not sure. I back probed and supplied power and ground to just the 2 wires for the one connector giving me issues and I used a 9v battery but only got a 3v reading. So then I checked the other shift solenoid harness connector and same thing only 3v. Checked the 9v battery and read 9.4v. is it only supposed to put out 3v or am I missing something

[@TBD3.0]

Great stuff👍🏻 I'm changing mine out this week hopefully; that'll resolve the issue.

[@ScottiesHobbies]

Good luck. Make sure those shift valves are moving. 💪🤞👍

[@robboid]

@@ScottiesHobbies Hey Scottie, is there a downshift solenoid in the 4l60E ?

[@justplanemike54]

Great video, can't believe i found it from all thats out there. My? I have a 99 gmc envoy 4x4 with this trans i believe. My problem is that it will not go in reverse. Before i found this it seamed to be slipping some going foward. When in reverse i can hear some winding noise. What could be the problem? Also note i believe i have some vacuum issues, (leaks) can this be a cause? Thanks

[@donnyevans11]

So leave the switch while changing solenoid?

[@RockymountainRobert]

My blazer is showing p0785 shift/timing solenoid, or 3-2 downshift solenoid, but the problem is My blazer won't shift into 4th gear, shifts up to 3rd gear and that it, the pressure manifold switch is what I replaced last ttime.

[@caseytinney4186]

My 4l60 stopped moving forward but will move backwards and I hv no 4x4 in my 06 gmc sierra

Where does this 1997 GMC 1500 5.7 LITER Vortec - OReillys - Power Torque 2 Terminal Transmission Control Solenoid - TE110 go for a 4l60e go in the transmission?

[@TheGeneralMotorsGeezer-we3dg]

I wish you would explain a P1870 code. I am having a hard time fixing it. Replaced the valve body, TCC solenoid valve. I dont know if it is the torque converter.

[@Garyrreitmire]

I changed mine what else should I try

[@danjim7056]

Still have a problem? Been 4 months but figured I'd ask if you resolved it. If you are issuing 3/4 gears the issue is likely burned 3/4 clutch pack.

[@mikemarch5480]

Hey Sottie, I am wondering if this is the transmission that is in my 2005 Chevy trailblazer 4x4? Please advise if you can, thanx.

[@MJsLandscaping-i9e]

I should also mention I have a no crank situation and the gear indicator has no line under P. It will only recognize reverse in every other gear position. Replaced the p/n switch twice, I read online from multiple people the car will still run even if cluster is out of the car so highly doubt it's a cluster problem. Could whatevers going on with the transmission harness be telling the car misinformation thus creating a no crank situation?

[@h.w.miller4180]

Does the epc solenoid (pressure control ) need to be programmed after installing a new one?

[@ant-hu1gs]

Is this the same procedure for a 4l80?

[@stoneyvill]

Can I replace just one shift solenoid? I have a sixth 6 transmission A solenoid control which gears 1-3 and B solenoid controls 4-6 and a separate solenoid control reverse. I don't know if that's how it works.

[@heavensfugitive6447]

I’m wondering how much of this great knowledge is also useful for the upgraded 4L65E?!

[@nsboost]

The 65 just has an extra planetary gear in the gear set. It’s not really any different at all

[@maestrotyper]

Hello greetings from indonesia....would like to drop u a question... is measuring resistance of the solenoid valve (Mv1 2 and 3) a right way to decide whether or not to replace the valves?

[@ScottiesHobbies]

I love that my videos get to help people worldwide. Hi there! You could. Or you can do a 9v click test.

[@maestrotyper]

@@ScottiesHobbies what i did was testing the resistance of the solenoid through the egs socket.. so i didnt get them out from the body valve... is that a correct way to do?

[@danchambers3236]

Hello....question about the a 4L60E trans. My 3-4 clutches are smoked. Everything kinda happened at once. Towing a camper, trans temp warning and while in D the trans will now not shift out of 1st. When in L2 it will do a 1-2 shift. When in L3 it will do a 1-2 and a 2-3 shift but when in 3rd it just free wheels the motor. It would seem it's time for a rebuild but I was wondering what would cause it to stay in 1st while in D. 05 Yukon XL 1500 4x4 for reference. No codes currently on the computer.

[@ScottiesHobbies]

When this happened to me, the check ball in the case was leaking like crazy! Only found out the check ball wad bad after I replaced the clutches and drove it about 900 miles and blew the new clutches out. We use to pull a boat and a camper a lot back then.

[@danchambers3236]

@@ScottiesHobbies Scottie....thanks. I'll look for that. I'm assuming I'll be looking for damage to where the check ball sits. I'm going to be a nervous wreck going through this thing.

Sorry, forgot to tell you, it’s a 2004 envoy with a 4.2 engine, blessings.

Check out this old video of mine. Be patient with it, I wasn't so good at talking. Lol. kzbin.info/www/bejne/lYjJhqKQaq-Mb7ssi=cuqy2UZl43Dj03yB I'd replace both shift valves and clean the valves in the valve body.

[@gabiladarlington1456]

Does the computer switch the power or the ground?

[@michaelgarza2837]

I hope this isnt too late to ask, but i just bought an 03 trailblazer and it runs good 1st and 2nd gear then won't grab third. I changed filter and filled with fluid and rides smoother just same issue with that 3rd gear not grabbing. Are the solenoids the issue? I was told that was the problem but dont have money to burn on "should be" guesses. Any advice would help a ton. Thank you

[@ScottiesHobbies]

Honestly.... you are probably going to need to save for a rebuild. It is super common for these trans to loose 3rd gear due to the check ball in the case no longer sealing.... this is a old video of mine, but it might help ya: kzbin.info/www/bejne/aYPanqWPa7aleNUsi=IL9pcIMWHa3BmA9L

[@RandalGraham-sb9kc]

Well I have a 05 trailblazer 4x4 and I was driving and it just stopped pulling all at once so I got pulled back home and bought all the selenoids and replaced them and fluid and still not going in gear what you think causes that

[@darrinweller5117]

Did you ever figure out what the problem was with your 05 trail blazer. My nephew has the same problem going on.

[@fredrobinson2198]

Hey Scottie, Just changed the solenoids and changed all of the fluid and the Tahoe is shifting like butter! Sorry this is really off topic but I need help! I have installed 2 Rostra neutral safety switches on my 2002 Tahoe 4.8 and they both have not worked properly. Wondering if I just have the wrong part. Do know if there is any difference between the Neutral switch modle numbers 24229422 and NS-85 or NS-85T?? Any info is super appreciated.

[@robboid]

Hey Scottie, I have a 97 camaro 3.8 v6 4l60e auto trans . I noticed the other day it wasn't downshifting when cold ,after driving a bit it went back to normal. I checked fluid level and it was down 2 quarts. Added fluid , still wouldn't downshift when you first start driving, then it works again. Then for 3 or 4 days it went 100% back to normal. Now it has stopped downshifting at all. If I kick it into passing gear it does, but during normal driving it upshifts fine but doesn't downshift whether automatically or if I manually try to downshift. No matter what gear it is in if I take my foot off the gas it acts like it's coasting in nuetral until I put my foot back on the pedal and give it gas , it then accelerates. I haven't gotten a check engine light or any codes. I was going to try changing the filter and fluid but i'm not sure if that will help.

[@NunyaBuisness-i3o]

Did you ever fix this issue??

[@Isaachedspeth]

Just curious, why do you only recommend that valvoline fluid over synthetic? Thanks

[@ScottiesHobbies]

Ya know... when I was doing my learning from the old guys back in early 2000's, they always recommend to use this fluid and I never looked back. I have heard the 4l60 series doesn't like the synthetic fluid but I've never personally tried it. I always thought it was due to the synthetic molecules being smaller that conventional.

[@Isaachedspeth]

@@ScottiesHobbies I have always been a fan of valvoline so that stood out to me, I appreciate the response. Would you recommend full synthetic on a 4t65e?

[@PenasGarage]

will 12volts work? instead of 9v

[@ScottiesHobbies]

I've heard 12v can damage a good solenoid.

[@thesetruths1404]

Great stuff. Does anyone know how to read GM Chevy obd1 transmission codes that may be stored? Hoping somebody had this exact issue and knows the proper fix. 4L60E automatic. 228,000 miles. Tranny shift delays from 1st to 2nd, when at any temp. Will hang in 1st until 2,700 to 3,000 rpm, and shift softly when it eventually upshifts. I can also get it to up-shift by slightly easing up on fuel pedal, at about 2,400 to 2,700 rpms. It will downshift as it should when going up a hill at around 15/20mph, 2nd to 1st. Reverse and 1st always work good, cold or hot. 3rd & 4th work fine. Fluid is exactly Full and clean, when hot/level. No Check Engine Light or any other warnings or issues. Anyone have this same thing happen and fix it?

[@ericp3573]

per what I read you have 1-2 and 3-4 on the back, in the front is the 3-2 for downshift

This place has changed a lot! I still love it here. My peers choose the wrong politicians, though. I'm blessed to have a great day job. No debt, thank god! I bought a truck on payments 22 years ago and when I paid that thing off, I said, no payments on anything ever again. I'm hoping to find a place in a rural area with minimal neighbors with a plan for a big garage or barn so I can put a lift in it and continue this side hustle. Steppin' in it! Tell me about it. I work in Stockton. This place is crazy. Sometimes I wonder how we are not in a 3rd world country. Caps at every turn. People doing crazy stuff. If my car was not parked behind a gate with guards during the day, I'd just leave my windows down and my trunk open. It's crazy!
