2nd gear grinding in LOW rpms, NOT high rpms

[turbolaserAWDrs]

Well, my friend bought a 92 laser AWD with a "cyclone swap" in it, he let me test drive it today and i figured that of course the synchros would be going so i took it easy and shifted at about 3k real slow and it grinded and i said wow, they're really bad and he said no it always does that so then i took off from a stop sign and shifted into 2nd at 6k and no grind at all...it consistently grinded at low rpms and not high...any suggestions?

did you ever figure this out?

it's not synchros obviously.

nope, haven't gotten it checked out yet..haha you having the same problem?

 

[eric95]

well i did like 5 things at once so one of them fixed it, now i'm trying to figure out what the hell fixed it. :]

new motor mounts
tranny mounts
gm synchromesh
cables adjusted
new shifter plate bushings
under hood shifter bushing (dsmparts.com)

now it works good.

i bet it was the tranny and engine mount that fixed it. high rpm the engine is tilted backwards, low rpm and idle the engine leaned forwards i guess cause the mounts were crap. so something wasn't in spec like this.

who knows go for the gusto and get it all done at once too, keep the mystery alive.

nevermind, none of that fixed it, it came back...

it's stupid, the more i beat the piss out of 2nd gear, the smoother my tranny shifts.

so as long as i haul ass to 6000 rpms twice during a drive, i'm golden.

heh, i'm gonna blow shit up i know it.
