I'll probably need more infer some someone to help me, but at least this will get the ball rolling………
My '84 truck originally came with a TH350 and a PO put in a 4speed auto. I haven't had the truck long and I would actually have to crawl under the truck and ID the tranny to tell you which trans I have. What I do know is it has an electrical connector on it which I believe is for a lock up converter.
Anyhow, in my continued effort to increase gas mileage, I was going to try adjusting the point at which the trans shifts into overdrive. Currently it seems to spend a lot of time in 3rd gear when it could be in 4th. Don't get me wrong, it appears to work flawlessly, but I would like it to shift sooner. What I don't know is, what inputs does the transmission consider before shifting?
If anyone can guide me in the right direction, I'm all ears.
Thanks in advance,
Stepperado
