Popping Out of First Gear.

[customs]

So for the first time I hit up the local drag way and had some transmission problems.

I have an 89 1jz swapped mk3. The car is simply BPU motor wise and the only upgrade in the drivetrain would be the ACT extreme pressure plate with the 6-puck disc. Running 245/40R18 bfg kdw-s on megan track coils. Now the problem is, when I dump the clutch first gear will pop out and go into neautral.

I did some thinking and thought that possibly this could be the result of the everything shaking around when the clutch engages. This happening because of old solf bushings in the rear end as well as motor mounts and transmission mount.

And discuss..........

No one has any ideas?

Worn shifter bushings, if not that, you have internal damage (worn/bent/broken shift fork, damaged gears, ect)

I had the same thing, when I took my car to the tranny shop, they said the shifter fork was worn and was causing first gear to pop out, but my shifter bushing were gone too.

^What he said.
Its a common problem with R series transmissions. Thats why Marlin Crawler makes this,

Alright sounds like ill be pulling it all apart this winter.

Might as well do a full rebuild with the marlin shifter fork, thrust washer and bearing retainer. I already have the shifter socket and shifter bushing.
It will be nice to have a transmission that shifts smooth.

Thanks for the input.
