Title: TCC issue after R&R of the solenoid
Post by: MetalBlue85GT on March 08, 2014, 11:20:46 am

I am going back in for another TCC Solenoid R&R and trying to locate a retail 3rd gear switch too. no one seems to carry these.

Here is the symptom:
- R&R TCC for the locking issue and that fixed the locking issue. Then after I installed the new TCC Sole I get a chugging of the car when I am above 35mph; cruise on flat ground. Once I accelerate or tap the brake or remove the TCC wires the chugging stops. So I know it has something to do with TCC.

So far:

Fluid exchange and filter replacement have not helped.

Anyone know of a good transmission shop for parts?
If I R&R the TCC Sole and the 3rd gear switch and it doesn't fix the problem: Anyone recommend a Transmission shop to rebuild this Automatic?

I bought my TCC Sole from Advanced Auto maybe that wasn't a good idea?



I have looked for some detail behind the purpose of the 3rd gear switch.

Does the following apply to our Transmission?

The 3rd clutch pressure switch is wired in series with the TCC lock up solenoid.The 3rd clutch pressure switch is closed by the fluid pressure from the 3rd clutch fluid to complete the circuit for TCC lock up.

Good discussion today - I will bleed my brakes for prep for next week and I will check the brake switch to see if that helps improve the problem for next week.

Glad we stopped in today good to see everyone.
