5th gear pops out - Toyota Nation Forum : Toyota Car and Truck Forums

I was wondering if any one could help me.
I searched previous posts and could find nothing.
I just bought a 1998 corolla with 5 spd manual transmission.
When I bought it, I never got it on the road, due to it was not licensed so I drove it around the guys yard.
After I bought it, I brought it to my mechanic and on the way there, I got it into 5th gear and it keeps popping out as soon as you give it gas.
If you don't give it gas, it stays in gear and if you keep your hand on the shifter, it stays in.
My mechanic said that it would need a new transmission.
I happened to do a google search and found this in Wikipedia:
"5 Speed transaxles C50

A 5-Speed Manual Transmission for FWD cars. This gearbox is known to develop a fifth gear pop out problem as it ages, primarily due to worn shifter detents caused by the driver resting their hand on the shifter. (This was supersede by C52 Transmission) Is used in the early mk1 (AW11) MR2."

Do I need a new transmission?

Anyone have similar issues?

Thanks a lot.
Could use help ASAP.
I have to figure my options.

Thanks,

Josh

I think it can be repaired with some new transmission parts.

BTW I think we have the C59 transmission.

Let me look at my FSM and find out which parts may be culprit.

Buurin,

Does the C59 replace with no issues the C50 (isn't the C50 what I have)?
Thanks,
Josh

Woops,
Didn't mean to reply so many times. I am new to this and I didn't know how to do it.

I believe Buurin is correct - the 8th gen Corollas (1998-2002) use the C59 transaxle. It is related to the other Cxx family of transaxles - but the C59 is designed (bolt pattern) for the 1ZZ-FE engine. The C50/C52 was setup for the A-seried of engines (4AFE/7AFE, etc.) - 7th generation Corolla and earlier, some MR2.

Need a bit more information - does the shifter only pop out of gear under acceleration? How about deceleration? Only 5th gear? Does the shifter seem to move an excessive amount? How does the shifter "feel" - lot of slop in there, hard to find gears, etc.

Without seeing it, could be a number of things. Sometimes it is simple as a shifter cable adjustment (linkage is out of adjustment) or the shifter fork itself is loose or the shifter bushing itself is worn out (bushing on the "ball" end of the shifter). Worse case, could be your input shaft bearings and/or intermediate/thrust bearings are shot and possibly chipped teeth as a result. That would definitely mean rebuilt or replacement transaxle.

Only pops out under acceleration. Shifts ok, is ok when you hold it in place.
Doesn't feel like excessive amount of slop.
