Default Re: Transmission after fluid change

If Wolfman's "fix" doesn't solve your problem, plan on replacing your valve body real soon.

That problem WILL get worse, due to internal wear and boring of the boost pressure valve.

If left to get really bad, the input shaft nut gets loosened, and that nut is no longer available from GM. It is also a torque-to-yield nut, which means it is not recommended to be reused, when you take it off the shaft.(Obviously it has to be reused now and even that is quite a process...)

The internal wear is caused by not changing the transmission fluid at the regularly-scheduled interval of 30-months/30,000-miles(whichever occurs first).

Lucas does work, and may provide a temporary "life extension" of your current valve body.
