I have an 1989 GTA 5spd......recently I started to notice whinning noise from the 1st and 2nd gear and also in reverse. Since I'm pretty sure those sounds arent good, I know I'm going to be looking at buying a new transmission soon. Does anyone know of a good unit I can purchase that will be a lil beefier and durable than the stock one? Also can it just bolt right in or am I gonna have to fabricate alot? All help greatly appreciated.

stock, you have a 5 spd, get a 6 spd.
you kinda answered it yourself lol

Or have Tremec rebuild it for approx $700 from what I've read on here and be good to 450 or so HP....

That way you bypass all the conversion stuff.

Or get a "built" 700R4 if you're tired of shifting it yourself. They bolt right up and use the same drive shaft.

No I want to keep the car manual.....its a rare combo GTA 5.7TPi T-Tops and 5spd. So tremec will do a rebuild for $700? Do I have to send them a core and they send me a new one or is the actual work done to my original trans itself?

Spectre

Is all that written in the RPO codes ?

If you get a trans rebuild, you sent the a core, if not, you'd be buying a rebuilt trans.

If you do a lot of highway driving.. or do autocross .. look into
the T5-6 as a second option.

THo if you get you're rebuilt for 700$ .. from tremec, I doubt its worth getting a 6 spd, unless you need the 6th gear.

From the factory a 350 would have had a automatic and as far as rare goes, I've seen a few 3rd gens that had replace their 700R4 for a 5 speed . You may want to look at you RPO codes as spectre replied to your post. As to getting a 6 speed, it would be easier/cheaper to rebuild the 5 speed to handle higher torq then to convert to a 6speed.

or he may have a 5.0 + 5spd.

When I first ran the RPO codes thats exactly what came up. I'll definately stick with the original 5spd that requires less modification, anyone got a good place to purchase one of these?

PS I think I run those RPO's again just to double check

Yeah, you'd better. No way the RPO's come up with 5.7 and T-5.... ypu've probably got the "F" engine (305 HO, possibly with dual cats)

tell us the Vin number that will tell if u have the 5.7 or 5.0

IEatRice4dinner

no 5.7L came with 5 speeds. eather it's a 350 with a t-5 swapped in or a 5.0L with 5 speed and a 350 swaped in if it is even a 350

the whining sounds tends to happen on highmiealige trans or if has been run low on fluid at one time mine did it not really a problem but a rebuild is a good idea id reccommend checkin ur tranny fluid first asap

GTA350VORTEC

Whats the fluid capacity of our TransMissions?

FndmntlsOfPimpn

6.5 pints

pasky

3.8 quarts I believe.

Not to say your 6.5 pints is wrong, I only know the quarts measurement.

FndmntlsOfPimpn

almost the exact same thing i jus rember thats what my owners manual said

DeWynter

Only test cars were built with 5-speed and t-tops, no productions. To belive that this car is real I would have to see a pic of the rpo codes and the vin.

Say what?? i have an 89 rs 5 speed with t tops and my rpos show both
