I am new to the fiero world and I am getting everything to gether for my build up. I am going to be doing a engine swap to a 3800sc series 2. I am going to want a manual transmission but I am not sure what one would be the best for what I am doing. I would like a 6 speed but a 5 speed is fine. Can anyone point me in the right direction.

if you have a low mileage 5 speed and the right clutch the stock getrag transmission will hold up to a s/c 3800. the stock 5 speed will also bolt up to the 3800 where as a 6 speed needs an adapter but the 6 speed us a much stonger trans, it can hold up to a well moded LS motor or at least thats what i have been told. so if you want to save some money keep the 5 speed but if you want an upgrade go with the 6 speed but expect to pay for that upgrade. hope that helps

Well, I sucsessfully built a 3800SC that destroyed my friends less than 10k mile getrag, and I only did 2 mods to it, (3.2 pulley and 1.9 rockers).

this graph might help you out. https://www.fiero.nl/forum/Forum2/HTML/087088.html

All of those transmissions but the F35 and F40 6speed bolt to a 3800. The F35 is by far the strongest transmission out of the bunch. On paper its twice as strong as a 6speed, and the 6speed on paper is at least 2.5 times stronger than a getrag.
