Stealth,

Wow, did you have bad shifting at that high of a temp? 240 is very high for trans. temps.

My old GT did that and it turned out to be a bad cat. converter.

43K a mix of getting on it and driving civil. Also doing manual down shifts. I want to change the fluid/filter at 50K.

I thought ATF needed to be changed every 30K. Am I wrong?

Well the fluid in our cars is a syntetic, It depends on what the owners manual says.

If you run the car hard then it's every 50K

If you drive normal (old lady like) then 100K

So if you are anything like the rest of us 50K is a good bet, or sooner.

Wow. That's good. I definitely figured it would be sooner. I had to do it every 30K miles on my Dodge Stratus R/T coupe (3.0L V6 / 4-spd auto).

Mine feels like you let off the gas during shifts, kinda annoying to watch the nose drop during shifts, but its always done that, hasn't gotten any worse. I don't think its handling the gears right.

Do you have a tune? Torque management cuts throttle back between shifts.
