Reverse Gear Problem

[545_TURBO]

Swapped manual gearbox from R32 RB20DET into ECR33. 1-5 gears work fine. But reverse gear can't be "fixed", it jumps back into neutral.

To move backward, I must engage reverse gear and fix it by left hand. What can happend with the gearbox?

ps. Sorry for my English, this is not my native language.

Your English is fine

Sounds like reverse synchro hub, could be selector too...I'm guessing your R32 box is second hand? Lucky dip with second hand boxes...you'll need to pull apart the thing to work it out I think.

Question, why did you swap the R32 box into the R33? Unless your R33 was originally N/A, the R33 turbo box is much much stronger and you'd be crazy to swap it for anything else in the Skyline range.

My ECR33 is daily driver and I don't planning any overboosting. And I think atmo gearbox will handle stock power levels.

But the problem is with the reverse gear. Don't know what should I do for now.

ps. Yep, the gearbox is from parted out R32.

It has probably broken the little spring that locks the selector into reverse.

2 choices - major expense to remove the gearbox to replace the broken spring. Or just put up with the inconvenience of having to hold it in reverse.

on a gtr box you can do that spring in about 30 mins without removing the box! im pretty sure a rb20 box should be even easier.

theres a little cover plate, if you take it out there's a mechanism and you will find the spring in there.

on second thoughts i'm pretty sure when that spring goes you can't select reverse at all..... might be worth a look anyway

Yeh, this is good known "reverse lock" problem. Thanks anyway, I'll try to check.
