hey, I haven't been here for a while! got some questions I hope to get help with. I have a '80 malibu with the factory 229 V6, with the 200 metric 3 speed. last year I added a few things to increase the power a bit, but made a few issues in the meantime. I added a posi unit with a 3.73 gear, dual exhaust with flowmasters, and an eldebrock intake and 4 barrel carb..500 cfm. the issue now is the shifting...when the car is cold, it doesn't want to upshift until it reaches way too high rpm's. it also doesn't want to downshift til later than normal also. when the car warms up after driving for like 30 minutes, it shifts perfectly! I changed the fluid and filter, although the old looked like new. it only has 34,000 miles on the entire car.
I know that the tv cable is what controls the shift points on this trans..when adding the 4 bbl, we spent a lot of time adjusting it til it shifted where we wanted it, but of course, it was warm. could this still be my trouble, or is it something else? any ideas and advice will be appreciated!
