Auto Tranny Performance Switch - Page 4

hbguy · 12-08-2009, 03:25 AM

Just bought the car, seems like its shifting in the higher rpm's. I believe its stuck in the 'performance' mode... it does so in 'normal' also. The light by the switch comes on / off but no other difference can be felt. Just wondering what you guys think it might be?

could it be that cooler sensor that's stickied in the 'how to' section?

its like most 4 cylinders, when the engine

is cold...they'll rev higher even when cruising to warm up the engine.

i noticed it was stuck at 3000 rpm's at a steady 75mph. it's about that at constant speeds in city also.

thanks

The differences can be felt at high rpms and heavy throttle.

Yes replace the ECTS.

3K is slightly lower for 75mph assuming DOHC engine and tranny combo
