Howdy!

 

REDLINE gearbox oil is a miracle cure for grinding gearboxes. A couple of the guys on the MR2 forum have used it with great success. One guy was contemplating replacing his gearbox, thought he'd try the REDLINE gearbox oil and it was a smooth as new!

sweet thanks man :lolcry:

:lolcry: Interesting. I have the same issue in my AE82 and from what I can gather its the synchros. Let us know how you go with that gb oil as I may try it myself if it gets the thumbs up..

I'm goin to do a 4agze conversion i have the money, soon to have the engine so i probably wont worry about the old engine and box now it will be for sale later. :lolcry:

The C50 g'box weak spot is the synchro between 2nd and 3rd. Too many quick shifts etc can damage the synchro. One of the best ways of fixing it would be to upgrade to the C52 and learn how to down-shift by heel-and-toe and learn to take it a little easier on the up-shift.

Or the preventive way would be to learn how to down-shift by heel-and-toe and learn to take it a little easier on the up-shift.

changing down gears is nice and easy and i worked out to stop grinding goin up gears do what ya said and just take it a bit easier. :jamie:

I have seen it somewhere here before I think but I can't find it now. What is the difference between the C50 and C52 box. What do they come out of ect?

i do believe the c50 is on the 4ac, and the c52 was on the 4age 16v in the ae92(I'm unsure where the else the c52 is used)

yep "c" series boxes come with that dodgy 3rd gear syncro stock!

no fix for it, unless you want to rebuild.

 

if using redline KEEP using redline. many many people have used it, then gone to something else and the box has died soon after.

 

i use ATF in my boxes. thats a c52 on a s/c engine with no issues

yeh i have the same problem with my AE92 corolla gear box the grinding between 2nd and 3rd i found that te faster u change the less noise it make and i change it slowly but it was worse rolla4 does using that oil actually work cause i would like 2 now.

C52 also came out behind the 7AFE in the AE102 and AE112

whats behind a ae92 4agze, not behind underneith :P and could it be a lsd

e5sumthing totally different from a c series box, completly unsuitable for N/A and none were ever stock lsd
