tranny

I have been having a little bit of grinding going into 3rd gear when going through the gears quickly, now all the sudden it is impossible to go into 3rd any way I drive. Is this just the synchro or is it more? Also where can i find transmision parts and how much they cost? Is this something I could do myself or should I have someone who does it alot do it?
thanks

3000's have a bolt on the back of the transmission that comes loose, its a common problem, check out this link http://www.3si.org/forum/showthread.php?t=301511

theres a whole bunch more info. and i think some pics if you search that site for "5th gear"

i would suggest not driving the car as much as you can to avoid costly repairs later and i'm not say this is your problem but just a heads up to a possibility

thanks I will look more into that tomorrow.

your 3rd gear syncro is going out, first try to put some syncromesh (i have BG SyncroshiftII and i love it) and see if it will work!!! DON'T go with the crappy ass GM syncromesh couple of people on 3si had problems with them. The BG is about $13 a quart depending where you get it and i think you need 2.7 or 2.8qts.

you can get your syncro's from http://supercar-engineering.com/sc/index.php?cPath=50

good luck


pm me if you have anyother questions

hey,

Im waiting for the BG synchro shift 2 to be shipped here and hopefully it will help out, Ill let you know how it goes.

thanks

I also found the fluid for 11 dollars a qaurt and free shipping, none of the auto parts stores around here had it.

where did you find it so cheap? you must share this wonderful information!

before i put my LSD insert in my tranny, i was using the GM Synchromesh (aka Pennzoil Synchromesh). and after hearing about all the bad experiences on 3si (although i found NO metal shavings and only had good things to report), i decided to switch over to a different, Synthetic fluid. BG Synchroshift I & II good choices, along with some Redline fluids, but just too costly b/c of shipping. I did, however, find some Royal Purple at $8 a quart at a local auto shop (O'Reilly's). that's what i'm running now and it shifts amazingly smooth, no grinding at all!

I found the BG Synchroshift 2 fluid at buschurracing.com. It was 11 a quart and they didnt charge shipping.

The product just says BG Synchroshift but the picture shows BG Synchroshift II. Isn't BG Synchroshift I just for automatic trannies and the II is for manual? Hopefully what you got is a II cause that's an awesome deal. I paid like $65 for 3 quarts so $33 would be SUPER! :p

Yeah when I was looking online I saw alot of places selling just BG synchro shift and i think it was for front wheel drive cars. When I saw this i thought it was just that but when I enlarged the picture it said otherwise. Also when I searched on this site for it, I typed in BG synchroshift 2 and it came up as a match. I guess time will tell. Ill let you know if it is what it should be.

hey I just gave them a call and it is BG synchroshift 2

My friend has the Royal Purple in his RT/TT and he loves it, i am going to change out my tranny fluid again (this would be the 4th time in a year, because of 2 clutchs etc. etc. etc.) and see how good it is. I probably have payed over $200 for BG Syncroshift in the last year alone :)

Awesome, thanks for reporting back. I'll know where to order from next time. Hehe :)

Not too sure here, but if the 3rd gear synchro is for both 3rd and 4th how come Im only having the problem with 3rd?

disregard the previous question, I got the impression that they were the same because they always say 1/2 nd synchro and 3rd-4th synchro. Ive been reading alot about the tranny and rebuild and what not. I now know

I changed the fluid and it is working alot better shifting into 3rd but its still bad, goes to show how incredibly bad it really was. I guess Im going to have to change the third gear synchro. Since Im broke Im going to try doing it myself since I have so much time and two transmissions. I have a 92 stealth tt parts car with a tranny but with that tranny it is grinding a bit into 2nd and 3rd but not bad at all. Anyone want to give me some feedback on this. I need to get the service manual before I start anyways. thanks

for transmission info, i've always gone to this site: http://www.vfaq.com/index-main.html, then click on "Drivetrain" at the top, then scroll down to the "Manual Transmission". i found several very detailed write-ups WITH PICTURES on how to install a LSD insert. i just perused it quickly, and there's a bunch of pics on the tranny rebuild. although you have an AWD 3/S transsmission, they're pretty similar to the DSM AWD transmissions. so those write-ups would be very very helpful.

also, yes, as you said, you should purchse SERVICE manual. you can get it here at www.manualcd.org. i have that manual on cd, and its amazing. its actually service manuals for a bunch of DSM cars AND the 3000GT (all models and years).
