TCC regulator and apply valve 4t60e


Does the valve body have to come off to replace the TCC reg valve nad TCC aplly valve with the Sonnax kit?


Yep… To leave the vb in would make it very difficult to use the reamer on it.



Transman Thanks for info
Is it worth installing the standard size or reaming a must? It is a 1997 there are no codes just shudder when hot.
