Transmission Shifting issue: need help please

[bartmanS4]

So obvious! It was there all along. Just ask Courtney Love!


Really? Nothing? I was laughing my *** off and patting myself on the back for that one.

Argh!

Not fixed yet.

So I replaced the mode selector switch, and its still missing a shift.
The only thing that I can think of is that I have the aftermarket offroad plates under the car, and its not letting enough heat dissipate from the area. Since the exhaust is pretty close to the transmission, it may be throwing too much heat at the trans.

If that is not the issue, my only option may be to have them start replacing solenoids in the transmission as one of them may have gone bad (according to the transmission shop).

Anybody have any suggestions?
Also, anyone know which solenoid controls the shift that happens around 27 MPH?

Frustrated.
