Default Overdrive?

My neighbor says that there is an overdrive that can be added to the end of a T350 tranny. Does anyone know about this that can share their experiences? Pros/Cons? Price? Thanks!! :flag

1980ZZ4,

I would rather see you go with a turbo700 with the 3.06 first and .70 4th gear.. It would be cheaper and easier to install!

Bob :cheers:

Not sure there would be enough room for the unit on these cars. It would at least require extensive crossmember mods. Better to swap to a 4spd O/D tranny like the 200R or the 700R.

Thanks to everyone for the information. I think I'll resort back to the 700R4. That was my first thoughts, but I didn't have any credible information and knowledge on this subject. Now I do thanks to you guys.
