Hello,
I am currently doing a restoration on a 1984 Silverado pickup. It currently has a 6.2L Detroit Diesel with a bank turbo, which is paired up with a TH400. I am hoping to do a swap on the transmission to one that has overdrive, as I was hoping to go above 55 without possibly causing damage. So moving on, the idea is what would be a better option: getting a TH700r4 and dealing with the shorter transmission, which would need an extension, and having to deal with a TV cable. The other option I was thinking of would be a 4L80e, which will require a computer.
Thank you
