Couldnt pay me to put a manual tranny in the trofeo.

taylor sometime we have to meet up and go there togther (the track) its like 25 min from me maybe the next import event? pm me if your interested

Still checking it out ...but the trnny you will need is the Borg&Warner one ..........i`m checking with Darryl weither this will fly or not......a young lad at work is a master-faber.... he`* puttin a jeep cheroke rear/YJ front in his 91 blazer *-15.........he said that it would be too bad a fit for tranny so i`ll get back when i can get the total picture

It would have to be a pretty strong tranny, being that the bonnevilles weigh almost two tons, if not more.

I know that there have been tensions bewteen CGP and here, but it has been discussed there, and the getrag would not be able to support the weight of the GP for that long, much less a bonneville. The programming is all in the Grand Prix'* PCM and you need a programmer to switch it which is pretty simple apparently (person with a cavalier put the L67 in his car with a DHP PCM and it worked like flipping a switch in the PCM).

GP vs Bonnie weight is nil really. 00+ Bonnies are way heavier then say the 92-95'*. They just kept getting fatter.

I looked into this for 3.8 period, would like in my old gen 1 H body LeSabre. there are alot of things I'd like to do though . Anyhow as Im sure most of you know its been done to 3.8 Fieros, thats where I got my information but I dont visit the Fiero sites. I guess theres two ways to go about the flywheel, one is machine a 3.1 to bolt to a 3.8 or machine a RWD Camaro 3.8 to work for a Getrag.

After that your golden until you need to do proper lenght drivshafts.

Then figure out how to make engine run proper with out auto hooked up to the computor

I looked into this at one time I was considering a TGP that needed trans anyhow. Knowing that gen 1 W bodys came with a Getrag I figured maybe swap one in a TGP. Very few of those TGP guys had at that time successfully done the transplant. At that time 2 yrs. ago no one had figured how to get engine to run proper without the ECM getting the info from the auto tranny. Certainly much has been gained in the knowledge department in the last few years. Obviously some Fiero guys must have a handle on the control module.
***TGP for those that dont know was a turbo 3.1 V6 Grand Prix made in 89/90 came only with the auto***

Theres a * 1 L67 Getrag Reatta just recently getting done.

When I asked the TGP guys if I could put a tranny from a V6 Beretta or Cavilier into TGP - They said it would be way easier to get W body donor and go dirrect. Because of half shafts, and some inner shaft in tranny is different. Cant think of what its called.

Now youve done all the research, spent all the money on used tired Getrag to find out you had to rebuild (I've heard #'* around 2500) , done all the fabrication, got er in there and rev your 340 ft.lp L67 up and let the clutch fly and WAM GRENADE your little Getrag clear out the back door of the garage.

I still want to try it though.

FRANKLY - If you want to get all worked up. I think it would be easier and more cost effective to - - - -
buy Corvette 6sp transaxle
reinforce unibody with mounts for engine and transaxle
place driveshaft tunnel
relocate gas tank or just get fuel cell
spin engine
place Paxton
Let the bird out of the cage.

hey, great idea!! i always wanted to see a bonnie with a 5-speed. We even have a third pedal to use as a clutch - the parking brake if anyone manages to get this done, my car is next!

SOMEday I wish/hope to do that. But there might be some big problems that could arise. Getting the whole clutch assembly to fit behind the 3.8 while not completely hacking up the firewall might be pretty tough. Then you have to deal with w/e is in the tunnel, since a torson tube (I am pretty sure that is what they are called) would then have to fit down there. Then a whole new rear suspenion setup because of the rear mounted tranny and drive shafts.

It might be easier to just find a whole corvette chassis, suspension, engine, and tranny setup and put all of it into the bonne as one big piece. (engine, clutch, tranny, and rear suspension) not to mention a LS1 powered bonne would be hella fun

A 5 speed would be pretty easy. PCM would be $35 + shipping. The only hard part is a 3rd pedal and shift linkage. And that'* just make a bracket, and get a cable to work for it, and get a linkage to fit under the car.
