1997 Chevy Suburban

My 1997 1500 Suburban with 45k on it began shifting hard from gear to gear after short non stop trips. You can stop at a gas station long enough to fill up, and when you drive off everything is like brand new -- until you drive another short distance and stop again.

Driving us crazy! No codes in the trans, and pressures and all look fine.

Anyone have this problem too . . . what fixed it?

    Define "pressures and all look fine". Has transmission line pressure been checked with a mechanical oil pressure gauge?
  • Yes. Transmission guy has checked pressures and all was within factory specs.

    He said everything "looked" and "checked out" fine.
  • I also have a 97 Sub - and have had similair probs.

    Mine would "slam" when doing 1-2 upshift. Hard - like I was worried about dusting the drivelines. Seemed to be worse when truck was stone cold - or very hot.

    Problem was the TCC control - this was replaced and prob has been gone ever since.

    Diagnosis of electronically controlled tranny problems is tough - find a GOOD shop and pay the going rate. If you go cheap on this - you'll chase it forever.

    Good luck- j4
  • I'm a moron- what is TCC control and what will it cost to replace?

    You're not a moron, Jeff, just dealing with unfamiliar acronyms. It's the automatic transmission/transaxle torque converter clutch solenoid. Depending on trans model, they're around $50-$75, plus the cost of a transmission service as the pan has to be removed for access. If the tcc won't disengage at low speed, the engine will stall when coming to a stop, similar to not depressing the clutch pedal on a manual trans car.
