Toyota R150F Manual Transmission Rebuild (Part 1)

Did our video help you? If so, consider buying us a beer: bit.ly/3feE6tJ
This is Part 1 or a 2-Part video series showing you how to rebuild the R150F Manual Transmission that came on the following Toyota models:
*1st Gen Tacomas w/ 3.4L V6 5VZ-FE Engine (1995-2004)
*3rd Gen 4runners w/ 3.4L V6 5VZ-FE Engine (1996-2002)
*2nd Gen 4runners w/ 3.0L V6 3VZ-FE Engine(1989-1995)
*This video will also help you rebuild the R151 Manual Transmission that came on the 1986 & 1987 Pickups with the turbo engine.
We were stoked to be able to partner with Nick at Yota1 Performance to bring this awesome series to you. We think it was very generous of Nick to be willing to share this tech with the DIY Toyota Automotive Technician Community.

$1700 seems like a pretty sweet deal to me. It’s not cheap, but if they do a good job and your 5sp lasts another 300k…

Nick at Yota1 would like to see the finished product too. It's coming pretty soon and you're definitely going to like it. The detail we were able to capture is pretty damn good. In Part 1, the parts were all black and dirty and it was harder to discern one part from another. Now with totally clean parts and some new parts, the level of detail went way up, not to mention Sean and I tag-teamed the video effort filming with 2 cameras to make sure we didn't miss any details. What I'm trying to say is it's worth the wait. Thanks for being a fan of this series. I like it when people are just interested in learning, like you are.

@@TimmyTheToolman will do Sean. I've sent a few messages on insta and here asking if you guys were going to do this and stokes to see it! Since I got my 01' Taco at 230k miles it's been making a loud waning noise from the transmission idling, 1-2, and 5th gears. If I put the clutch in it's not heard. I think it might be some of the needle bearings or maybe the input/output shaft main bearings. Replaced my clutch release and pilot bearings and still heard. Did you guys hear a rough estimate as what mileage for to when to rebuild? I'm at 281K right now. Also interested if you've heard about the waning, I've heard it many other R150Fs (tacos and 4runners). I'll let you all know which bearings were the culprit once I get it done.

I believe this transmission came in the T100 also.

[@TimmyTheToolman]

That I'm not sure of. I'll ask Nick and report back.

[@definitelynotpewdiepie]

​@@TimmyTheToolman R150Fs can be found on Toyota T100s with the 3VZ-E and the 5VZ-FE. I own one with an R150F on it. There are 3 different versions of the R150F transmission. Version 1 (1988-1995) has the short input shaft and a tailhousing for the passenger drop transfer case found in Pickups and 2nd gen 4Runners. Version 2 (1995-1998) has the newer long input shaft, but the old tailhousing. This is the rarest version because it only ever appeared on T100s with the 5VZ. Version 3 (1996-2004?) has the long input shaft and a tailhousing for the driver drop transfer case found on Tacomas and 3rd gen 4Runners. This is the version featured in your video. The gears on 1986-1995 R-series transmissions cannot be fully interchanged around with late (1996+) R-series transmissions because Toyota changed the helix angle on the constant run teeth after 1995. This basically means that you can't build a T100 transmission by swapping the input shaft from a 3rd gen R150F into a 1st gen R150F. Legend says you can swap tailhousings and build the T100 configuration from a 3rd gen R150F that way, but I have not personally verified it.

regarding the bearing splitter 25:37... as far as i know a splitter of that size is pricey, couple hundred dollars... the spiltter available for rental at the McParts store is literally half that size!

[@TimmyTheToolman]

I wasn't aware of what size bearing splitters were available for rental from auto parts stores. You are right that a quality bearing splitter of the size used at that time stamp is in the neighborhood of $200. I own this kit and it would pull off that bearing: OTC 4517 Puller Set amzn.to/3bdlB1N Having the Right Information is only one piece of the puzzle. You need the Right Tools and tools are an investment. These tools cost money up front, but they will save you a ton of money in the long run. Lots of times, the first time you use the tool to enable you to do a job yourself instead of having to pay a shop to do it for you makes the purchase worth it because of the money you saved. Shop labor rates are high. My local Toyota dealer now charges $300/hour.

[@efil4kizum]

@@TimmyTheToolman 300$ ouch! that is unreal... my local dealer is still at 160$ and was 140$ a few years ago. the bearing splitter I was interested in getting would be one that can pull a stuck wheel bearing off of the hub if it chooses not to press out cleanly

Love your videos and went with Yota 1 for my engine but man do they lack any sort of customer service. Cant get a call back or information about my refunds... Keep up the great content!

[@TimmyTheToolman]

What problem are you having with your refund? Are you talking about the refund from returning the core engine? I would call and ask to talk to Rebecca. They recently had a long time employee quit who was working in the office and they are training up a new lady. That might be the reason for the delays in getting back to you. I know Nick and Rebecca well and they are good people. They would not purposely hold onto your money. Also, sometimes people don't get a full refund on their core charge. The reason is damage to certain components of your engine raise the cost of them being able to rebuild your engine and resell it. Again, call and ask to speak directly to Rebecca and she will sort it out with you.

I know this is off topic so I apologize. I have a 2003 Toyota Camry Xle 3.0v6 with 130,000 miles. I don't know the history but I really want to change the transmission fluid or should I? Do I just do a drain and fill or flush? And should I change the filter? I don't have a owner manual and I can't find out much using this internet thing. Could you please give me some much appreciated advice? Thanks

[@TimmyTheToolman]

Just do a drain and refill of the pan. That's safer than doing a full flush on an unknown maintenance history vehicle. After another 5k miles or maybe at your next engine oil change, do another drain and refill of the pan. Then follow that up with another drain and refill at the same interval. By the 3rd round, your fluid should be in pretty good shape. Then, do a drain and refill every 10k miles after that. Drain and refills are a dilution process, but they work really well to get the fluid in good shape.

[@dannycolemire2652]

@@TimmyTheToolman I'm sorry just to be sure are you saying don't drop the pan? And don't replace the filter? Just remove the drain plug and refill? Thank you so much for getting back to me it means alot and takes alot of stress off my mind.

[@TimmyTheToolman]

@dannycolemire2652 Those filters are a fine metal stranier, and they don't clog that easy, but this is what I'd do. I'd base my decision on what the fluid looks like. If it looks really bad, dark brown to black in color, I'd drop the pan and replace the filter because really dirty fluid would create more deposits in the filter. If the fluid color is pink to a dark red, I wouldn't bother dropping the pan. The filter shouldn't be clogged at all.

[@dannycolemire2652]

@@TimmyTheToolman Tim I'm so sorry to bother you but its really hard to find information on my 03 Camry Xle 3.0v6. So I'm going to take your advice on the drain and fill like you said. Just one last question after I drain the fluid and I'm refilling it how should I go about it? Should I put a couple quarts in it and let the car warm up before checking the correct level on the dipstick or can I check it cold?

[@TimmyTheToolman]

Add back in the same amount you drained out. Confirming the fluid level can be done when cold or hot. I like to dial in the level when at operating temp. Drive the car for around 5 miles out and then 5 miles back and get it on level ground and check the fluid level. The vehicle needs to be driven for the fluid to warm up. It can't heat up by just sitting there idling like the engine can. After you drive, you'll want to see the level on the dipstick between the hot hash marks.

[@dannycolemire2652]

I need everyone's help that knows about Toyota's please if you wouldn't mind. This is a long story so please bare with me. I drive a 2003 Toyota Camry Xle 3.0v6. I had new brake pads on all around and had perfect brakes could stop on a dime with barely stepping on the pedal. BUT i realized that i had more of a metal pad put on instead of ceramic so me being OCD and having bad anxiety decided to buy another set and have them put on just so the metal ones wouldn't eat up my rotors so fast BIG MISTAKE! My normal mechanic called and said your car is ready to pick up. So before getting 3 miles down the road i started smelling something burning so i stop and checked and my back wheels both sides were almost smoking. So i had to wait until the next day to get ahold of my mechanic and he says both my calipers must be stuck or sticking lol. Keep in mind i had perfect brakes with no issues until having those 2nd set of pads put on. So i had no choice but to have calipers put on the back which i had to borrow the money to pay for. So he once again calls to say you car is ready. So driving back home i came to a red light and my car stopped me fine BUT my pedal started sinking almost to the floor. So i called my so called mechanic and we went at it and he said bring it back out here and i did. Two weeks later he calls me saying ive put different rotors on and tried 2 different master cylinders and nothing helps with the sinking of the pedal. So does anyone have any ideal? Did he not bleed them right does my car require ABS Bleed what could it be? He said he checked everything no bad lines no leaks so please help anyone?

[@TimmyTheToolman]

The mechanic didn't bleed the system properly. While replacing the calipers, if he didn't cap off the brake line and let it drip for a long time, he could have emptied the master cylinder introducing air into it. If that happened, he would be forced to bleed the master cylinder. Air could have also been introduced into the ABS pump.

[@dannycolemire2652]

@@TimmyTheToolman I really do appreciate your help and I so wish we had good mechanics like you around here in Kentucky. We might have some but I haven't found them. So what would you suggest I do I have a friend that can help me bleed the brakes but if there's air in the abs system I'm assuming that takes some type of computer. So if I took it to maybe a Toyota certified mechanic that I really can't afford should I just tell them what you said? I'm sorry for being ignorant when it comes to this kind of thing. But you're help takes away some of my worry and puts me on the right track.

[@TimmyTheToolman]

@@dannycolemire2652 I'm not sure if your vehicle requires the Toyota Tech Stream program to bleed the ABS system. I know you can force air out of the ABS module by getting the ABS system to fire. You can do this on a gravel road and do some hard stops to get the wheel to skid so the ABS kicks in. This will push the air out of the ABS module and into the brake lines so you can bleed the air out. Your first move would be to find out if the mechanic actually bled the master cylinder. There's a process for it. If he doesn't know what you're talking about, he didn't do it. Your original master cylinder was probably fine. It's just that the guy introduced air and caused the issue. At this point you have nothing to lose by trying to bleed the brakes yourself and see where it gets you. Start at the right rear, then left rear, then right front and finally left front. Move a ton of fluid through the system. It's going to get boring for the person pumping the brake pedal for you, but that's my best advice for now.
