Transmission poping out of gear

[guntop116]

I just put a sr20 back in my car and after getting it running i went out to drive it. Now every time i go into 4th gear and let off the gas the shifter pops back into neutral. The thing is that i had the same tranny in the car when i had my other sr and it never did this.
Any ideas?
My tranny mount is kind of worn out, if that makes a diff.

The sudden jolt from letting off the gas with a worn tranny mount could be enough to literally "pop" your car into neutral...

Try replacing the tranny mount, and see if that helps. Thast what it sounds like to me at least. Ever notice that jolt you get from being in gear then just letting off the gas? Thats what im talking about.

do you have a short shifter? my brother bought a cheap one and had it too tight and had this problem.

No, i still got a stock shifter. I got a nismo tranny mount i just forgot to put it on when i did the swap so i used the old one. I was kind of guessing that was the problem. I guess that gives me something to do this friday.

worn transmission sounds like the problem. doubt the mount itself it the whole cause of the problem.
