Looks like the Main input shaft bearing or TC is going fast. 4L60E. Century built.

I took a hard right turn to get out into traffic. It went fine but then made a pop and a feeling like beeing totally disengaged and I heard a Whine. At 1st I thought the Eaton POSI had finnally blow itself out (about to be replaced with a spool here soon), but when I gave it a little gas at the light the car moved so I thought it might be OK for now.

Now. When I gave it gas it rev's up to Red-line and won't shift. It also has a High pitched whine like that of a Turbo (bearings) and it will only shift if I let off the gas. The TC still locks up and I still need to drive it around and get some other symptoms, but I think the Trans Input Shaft bearing is shot.

About to check the fluid in a little bit to smell it and to see what else might be in the fluid. Seems Shot to me.

Ok. Nothing in thefluid and it doesn't smell burnt. It still whines in Park but not as much as Driving. I think the trans is done for.

Looks like the Front pump can go out also.

OK. Maybe not the Pump. Or the TC. I have no Reverse. I didn't notice it before beacuse I brought it straight home. Tried to back out of the driveway and it's no go. ****.
