Standard trans? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

fire235 · 12-24-2004, 01:11 PM

What is a good manual shift trans for a 307 or 350 engine? Also how hard is it to swap from an auto trans to manual shift trans? The truck was originally 3 on tree but prev. owner swapped to turbo 350 auto so the clutch pedal is already in the truck. I am considering manual with floor shift. Any Thoughts?

Have a safe x-mas.

I am in the process of swapping the old 4-speed out for A TH400. My preference. I like the idea of putting A newer 5-speed from A later model truck. I dont know what is involved. (crossmember attatchment). Good luck!

Do a search on t-5 If you want a five-speed. The later model trucks 5-speed has an electric spedometer Which I hear can be pricy to convert

I will be taking the turbo 400 out of my 3/4 ton one of these days -if I can ever find the time- and putting in a Muncie sm-465 4 speed. It has a good reputation, tough as nails they say. You will probably need a drive shaft from a standard trans truck, a manual trans crossmember, clutch pedal and all linkage (z-bar, etc.) Also, you will need to drill and tap a threaded hole for the z-bar into the block (drivers side) unless it's there already. And I beleive the neutral safety wiring will have to be changed to a manual set-up. The low-hump trans cover will have to be changed to a high hump. Can't think of anything else. Best of luck.

I'd recommend against the T5. They are a light duty transmission & will not stand up 350. I wouldn't put a T5 behind anything bigger than a 6 cyl.

I swapped out a 3 spd Saginaw with a 4 spd Muncie. Easy swap with no problems. The engine was originally a 307 thap was pulled and a 350 installed.

If you have $3000 burning a hole in your pocket, search on Richmond 6-speed.

What corssmemeber did you use? I just purchased a M21 and need to get a crossmember for the tail. It currently has the 3spd in it. Thanks in advance.

Either the TR 3550 or T56 conversion would work great. Been thinking about either for my next project.

I want the T56 bad, but it'll have to wait for awhile.
