Title: 2.5 t/c lockup
Post by: mark3 on 03 July 2009, 18:31:50

Hi all, i have a 97 2.5 V6 auto estate that has never seem to have had torque converter lock up! when cruising at speed and the throttle pressed the revs increase momenterily then return to where they where before increasing with road speed!

is this a common fault and if so anyone know if theres an obvious repair???

The T/C Lock should kick in at 50mph, providing your using lightish throttle, and not going up a steep hill!

Also, it wont lock if its in '1', '2', or '3' or Sports Mode

I would check oil level in the box first and take it from there.

Thanx for the reply, the fluid level is ok and i sort of guessed the rest. is there a relay for this, or an auto ecu i can look into? i have very little info on Omega auto trans operations!!

Sounds like normal behaviour to me. It goes out of lockup momentarily with a quick change in throttle. If you gently squeeze the throttle at cruising speed > 50 MPH, does the RPM immediately increase or follow road speed?

Lockup is not a separate function with an electronic gearbox. It's controlled by the ECU along with the rest of the gearbox. If you still suspect a problem and fluid level is OK the next step would be to get it on a Tech 2 and look for trouble codes in the gearbox ECU IMHO.
