My truck is a 68 Chevy C/10 shortbed stepside.
I have a 3 speed on the column transmission hooked up to a 78 Chevy inline 6 with electronic distributer. I had replaced it with that engine when I cracked the head on the old one. Just putting that in there in case it may help with mating up a different transmission.
I cant deal with the low speeds on the truck anymore. At 60 MPH the transmission complains. I want to be able to do 70-75MPH.I think I want a modern automatic. I wouldn't mind a 5 speed manual if it has OD, but what do I have to do?
Does the whole rear axle have to be switched if I put in a 700R4? Or can the rear end just be changed internally?
What has to happen if I go with a 5 speed? Does a hydraulic clutch have to be put in?
Any driveshaft concerns on length or crossmember modifications required on this year of truck?
