Toyota Truck manual transmission oil replacement

Replacing gear oil in manual transmission on 1991 Toyota Pickup, using full synthetic 75W-90 Gear Oil

[@bradensmith888]

My 1996 T100 4 cylinder 5 speed rwd took 3 quarts of Redline MT90 GL4 synthetic gear oil, and it's shifting much smoother. I highly recommend against using GL5 fluid in these transmissions

[@pedrofernandez8729]

This just proves once again that these trucks are indestructible, even though it is neglected.

[@robertsawa3407]

The rust belt destroys Toyotas the same as any brand, salt makes them quite destructible.

[@pedrofernandez8729]

@Camaro 1968 I don't make them and I don't own the company, all i know is that the whole family has been buying Toyota for many yrs and all have been trouble free. I'd say there's been like 8 all together.

[@GC-kw1gq]

Rust Belt is tough place grrrr - but does not damage internal drivetrain assemblies as much as chassis etc. Toyota drivetrain are built Ford Tough

I just love those 1990's Toyota 4 cylinder trucks. In today's world, everyone wants big V8 trucks but those 4 cylinders from Toyota run forever and get great fuel economy. Awesome video.

[@silverthirty5262]

Yeah they Last forever I have a 1990 22re original engine original transmission 500,000 miles runs like a champ Just have changed wear and tear stuff that’s it

So clean for a 29 year old truck. I'm officially jealous here in NY

[@1xicano]

I have the same 1991 Toyota Pickup and the correct oil to use is GL-4 75w-90. I too made the mistake of putting the synthetic GL-5 75w-90 gear oil in the transmission but luckily I discovered my mistake in time and i changed it out to the correct GL-4 Synthetic 75w-90 gear oil. Truck shits great no issues.

[@eduardorecinos1469]

My favorite internet moment is when Peter begins draining fluid and sees how filthy it is.

[@isaacrosales1887]

Excellent video, I did mine a few months back however the transmission I owned is from a RN80 so it had soft metals in it, hence I purchased online GL4 fluid to help to preserve the transmission for a few more years. Toyota Manual calls GL4 or GL5 however its known that for soft metals within manual transmissions to use GL4 instead of GL5 due to the GL5 additive being very strong for those soft metals so GL4 is the way to go but is harder to find. Thank you for your video

That was astonishing. It looked like pure mud! Once again, it's awesome to see how easy this stuff is. This was almost easier than a regular oil change because there's no pesky filter to get at.

Wow that fluid was ancient. I felt guilty once when I skipped the 2 year fluid change on the differential and transmission for my 2004 German Spec'd RAV4 4wd 5sp and waited one more year. The fluid still looked pretty new unlike the chocolate milk pouring out of this one.

[@melodicman3032]

I have found out that due to the parts in the manual transmission G4 is really a better choice due to ease of shifting gears. It has something to do with the syncros that involve shifting gears smoothly in the transmission. I have a 1993 4X4 DLX Pickup and I will be changing my transmission oil from G5 to G4

[@4af]

Right. The poor owner of that '91 now has to deal with difficult shifting because a GL-4 gear oil wasn't used like Driven 80W-90 or RedLine MT-90 75W-90

I have a 2002 Tacoma 2wd 2.4L manual transmission, about 190k on the odo. Bought it brand new 18+years ago. I am crying already that the manual is no longer available in any other new truck except for the Tacoma and by the time I'm ready for another truck it won't be any longer.

[@rightlanehog3151]

@@christianjensen3182 The good news is that yours should still last many more years. BTW every once in a while a genuine, low-mileage Tacoma comes on the market and the manuals definitely take longer to sell than the automatics.

@@christianjensen3182 However with the reliability of them, there will always be used and by the time that used one dies you never know what will be out there. Why your love for the rear and manual? Nostalgia? Simplicity? Fuel savings?

Nostalgia I guess. Every vehicle I have owned since 1977 (when I got my first car) has had a manual transmission. I would like to finish out my driving life still driving a manual transmission.

No filler all meat great job

[@erictechz5288]

Redline MT-90 is great oil to use.

[@alporroing]

Valvoline is GL-5... every manual transmission says "NO GL5" only GL4 or 3... see where im going? Because the additives specific to GL5 damage the synchro cones. Even says so on the Valvoline bottle.

[@dquad]

OEM repair manual for Toyota G/W transmissions actually specifies "GL-4 or GL-5 oil"

[@alporroing]

@@dquad cool. Mine says Gl-3/4 ... and the valvoline bottle says "NOT for Syncronized manual transmissions"

[@jonasthemovie]

It is yellow metals that are damaged from traditional GL5 oils. GL5 is a performance level, not a formula. Some GL5 oils are safe for yellow metals, some gearboxes don’t care if the EP package is there.

[@isaacjrv]

You will find in the owners manual gl4/gl5 however this was a believe back then that was no issues later manuals were updated after discovering gl5 was damaging the synchro's. Gl4 for the win, but is getting more difficult to find cheap. Make sure that says gl4 and not both. Red line mt works but is a bit more expensive.

[@juliorebollo7496]

very nice interesting video and very well explained greetings

[@stonewalled9696]

I don't have a manual, but my understanding from a Toyota Master tech is that GL5 will eat up your soft metal gears and is not the recommend gear oil due to the aggressive additive package and should only be used on differential and Transfer case. Only GL3 or GL4 for the manual transmissions, if that's what it calls for.

I was wondering, before putting the drain plug back on, would it be a good idea to put in a little bit of new gear oil in to help flush out the crud?

[@markreynolds3850]

Is there a vent plug on manual transmissions?

[@shiddy.]

anyone getting ready to do this ... please don't ever use GL5 gear oil in any synchromesh manual transmission - it has double the EP additives as GL4 and it will eat at the brass and other yellow metals that the synchros are made from if you do this by accident, it will withstand a lot of damage before you notice anything is wrong, but the clues are milky yellow or golden junk in the oil when you change it, and if you open the transmission, you'll find that the synchros will have turned from shiny brass to black from it we love these trucks, don't let that happen ... only use GL4 fluid in the manual transmissions ... if the bottle says it's both GL4 and GL5 compatible it's just wrong - they are different fluids personally I use redline MT90 GL4 in 75w90 weight for my 08 tacoma 6-speed ... the price gets better if you buy a 2 or 4 pack of the quarts hope this helps - good luck out there

[@jdmDC2ftw]

Is it okay to mis different brands of gear oil? I have a bottle of mobil1 and 2 bottles of Valvoline, both 75-90.

[@andreasm2882]

I have a 2019 TRD 4x4 with almost 20,000 miles. I will be doing the diffs and transfer case in the next 10,000 miles. My issue is finding the correct oil not even the dealer is using what is stated in the manual. For front and rear differential it is supposed to be 75w-85 and for the transfer case is supposed to be just 75w. The Toyota dealerships in my area are using 75w-90 for front and rear differential and transfer case. Also independent Toyota shops. I can't find the correct fluid anywhere but I am able to find the diff fluid I need from Redline and the 75w directly from Toyota on-line. I just think it's very strange that the dealerships are not using the actual recommended fluid, what do you think??

[@yarpos]

Can you flush out the remaining gunk or is that likely to stir up trouble? thinking diesel or similar. Just asking as I had an 1960 car I was bringing back to life and the trans oil was ghastly like that and of unknown age. After the change I did another 2 cycles of cheap gear oil about 3 months apart (low use car) and the put my preferred stuff in. As you would expect it improved each time, but gear oil aint cheap. The box reacted well to the love :-)

[@LAactor]

There's a guy in the UK who redid a daihatsu with the stuff. I can't see why not. As long as you don't let the diesel sit too long. There isn't much gunk left by that time and if you felt there would be some stuck in there, the slow dissolving way is the best like how you're doing it and open it sooner than the change interval and see. If it's cloudy and no longer yellow, change and you will see it not getting dirty as fast. That's the best way. No shock to the components or risk of a chunk coming off and grinding off a component inside. Unless there is major problems that you know will be fixed and need fixing or else and you are willing to take the risk, why not. Be a learning experience. Report back if you do. Ever think of MMO? That's the most aggressive I'd go. Concerned about any seals on something 60 years old.

[@Luckingsworth]

I would think a change followed by driving for a few miles then change again would be safer and have similar results. Lots of detergents in these fluids already.

[@fm1224]

Use regular engine oil for the flush
