Re: tranny help please
The pressure regulator valve is at the front of the valve body, right next to where the filter connects to the pump inlet. It's held in place by a snap ring. I don't recommend removing it unless you have some experience with the process. The valve assembly is made up of 5 peices. If you wish to proceed, please take care not to lose or or mix up the peices. One possible cause of the buzzing noise is also a stuck vane in the pump itself. I recommend servicing the trans and adding 1 bottle of Lubeguard Red to the fluid along with replacing the regulator assy according to the TSB.
