Tested the front pump pressure today, doesn't look good. at idle R- 72, N-60, D-60, L-60. When I rev the engine the D and L goes to zero. The readings with vacuum hose disconnected is R-110, N-90, D-90, L-90. Wheels rotate when in N.

Why do you say, "doesn't look good?" Other than reverse with the hose disconnected all the other pressures seem relatively in spec. At least it seems to indicate the pump is working.

Your chart is different than what I have. I'm using 65 manual, page 7-55.

For sure they are different. I took a quick look and didn't see what year and assumed they were all the same ('61 my manual). Still other than reverse (low at idle) the numbers are relatively close to the low side.

Since you bought the Trans from Clark's, I's suggest you first all them and see what the technical help that can give or if a warranty exchange is in order. I would not advise opening the trans as it may void warranty.

I'm highly doubtful that they would send a trans with a stripped shaft or tabbed washer/pump drive. I don that the if you are not careful when installing the TC to the tansaxle or installing the trans on the Trans Axle with the TC already installed, you can bang that pump drive shaft and pop the snap ring off the end that will allow the tabbed washer/pump drive shaft to walk off.

My next step would be to pull that front pump cover of and see whats going on with the front pump, but not unless Clarks gives you the OK to do so and its documented. Else, as I stated, it may affect warranty.

I would be more to suspect, a missing check valve/ball or spring somewhere in the system, but as you responded to my question about the fluid level not changing Running vs Not running it seems to point to some kind of issue with the front pump.

Call Clark's before you do anything else.

That's a problem for sure.

Early and Late PG transmissions are different, they upped the pressure in the LM trans to handle the added torque of the bigger engine, that said, his pressure checks were not in spec at all. My guess is this Valve was left out of the rebuild, there is also a small washer that goes under it to limit the amount of ATF that passes through it.

Seems like alot of work if Dave is correct on missing part diagnosis. Will Clark's honor warranty if front pump cover is removed in the car?

Everything is out of the car. Will talk to John tomorrow. Observation, when I spin the input shaft I hear clicking within the case.

This what it looks like with front cover removed. As you can see I don't have the valve or a place for it.

I thought that check valve is only for the trans cooler option on vans?

No. It has been in all the Powerglides I have taken apart and none of them were FC.

In case you get up before the others here... (who know far more than me), release the clip on the shaft and pull off the washer with three tabs. If either the spline on the washer are damaged..., or the splines on the shaft are damaged that is at least one of your problems. I believe there is a clip on the other side and if it is missing (as in broken off or never put one) that could be a problem too.

Also, not that is should matter but mark the positions to identify a tab on the pump gear and the spline position with a marker. SOMETIMES that helps to solve a problem though I doubt it here.

It does have both clips. I packaged it up, will take to UPS store to send back. Clark's said they will send me another one. Thanks to all for the help on this matter

I believe that the primer valve (I think that is what it is called) was added in '64 as part of the changes for the larger engines.
