I am wondering if anyone can give me a diagnosis about what my transmission is doing. I have been meaning to take it to my buddy that works on transmissions but he is backed up.

Shifting into all of the gears is fine except for overdrive. When I get to 45 - 50 mph and it shifs, I feel a jolt and it feels like I about to take off for launch and then its fine. I'm not flooring the gas, just driving normally. This happened maybe once in October and it didn't happen again until a few weeks ago and is still occurring.

Anyone have any ideas?? :confused013:

I'm not a tranny expert but I read in my research about our trannys that the o/d accumulator is responsible for smooth shifts into 4. Like it cushions the hydraulic pressure for a gradual shift. I don't remember right now if there's a way to test the accumulator.

At least your O/D works...
