Hello all,

I wanted to update this thread for the common knowlege. I also have a new issue unfortuntely..

I ended up taking the valve body apart in my old transmission, cleaned it very well, found a few sticky valves, put it back together and.... no change.
Total pressure still very low, I'm assuming the pump had failed but cannot confirm.

I then decided to replace the transmission, and do it right with a rebuilt unit from Sun Valley. A friend of mine graciously offered his help and use of his lift. Took us 2 hours to get the old unit out, and 3 hours to get the new rebuilt unit in. "While I was in there" I did the flex discs, and the rear centering bushing on the drivshaft that was damaged.

So now today: Took it for a long drive and got the fluid level dialed in to perfection. It shifts well, but now I have one new issue:

At 55mph+ I feel a subtle pulsing vibration, about twice per second. It's more pronounced the more throttle I give it. It's pretty mild, I doubt my wife will notice it, but it bothers me for sure.

Perhaps I did something wrong with the driveshaft? I marked the halves and put them back together properly. I also torqued everything down to proper spec. Any ideas what would cause this vibration?

TIA!
