Hi guys, im having a problem with my transmission i think. First off I have a 94 B4C camaro with the 4L60E and 3.42 gears and when im cruising on the highway and i try to accelerate the cars jumps down a gear and revs up but doesnt accelerate until i hit more than half throttle, then a clunk and the car accelerates. Another thing, i can be going say 45mph in "D" then i can downshift to "2" and the car doesnt enagage the gear, it's as if i hit the clutch on an M6, the rpm's drop down to idle until i hit the gas, then it engages the gear until i back off the throttle again, it's really annoying. And one last intermittent problem, on very cold morning's sometimes it doesnt like to shift out of first gear for a long time, doesnt matter whether i back off of the gas or not, until i get like an eight mile down the street, then it shifts into second and shifts fine the rest of the day. The only things done to the tranny are a fluid change to B&M trick shift when i bought the car and a hypertech PP3 with the shift improvement set to on, i tried it off too, same problem though. It didnt start until like 4 months after i had the fluid changed and the programmer programmed. Any help in this matter would be greatly appreciated as its almost warm enough in western NY to put the car back on the road Thanks in advance.
