Neophyte questions here -- I have two tranny books on order but I am dying for more info.

Picked up a C4 off craigs list yesterday. Out of a 79 Mustang, was behind a 302. It had been rebuilt 1 year before the stang was wrecked.

Still had nice cherry oil in it and turned freely, shifted through positions.

But the casting numbers were accross the chart.
PUMP: RF C4AP 74105 A
CASE; D2CP 7006C
SERVO: C6AP 7D027 C

I measured the input shaft and its .839, so its not a pre-70 tranny. But does that mis-mash of numbers make sense?

Finally, and why I really posted. It was full of oil and still had torque convertor and bell attached. Which made it a bugger to move by myself.

So I drained the oil via the TC, removed it, and proceeded to remove the oil pump bolts with the intent to remove the bell housing. Except when I tugged on the bell, I got the oil pump along with it.

Like I said, I don't have a book yet. Once I had the bell and the oil pump separated, I slipped the pump back in and it seemed to go in fine. I put the bolts back in and tightened them only enough to keep the dust out. Or so I thought. When I tried to spin the tranny and shift, it was tight, no movement.

So I loosened back up the bolts and now it turns again, but less freely than before, and with some grating. Of course, there is no oil in there anymore either and the TC is gone.

What did I do? I am planning to rebuild/refersh the tranny anyhow, but this would seem to be an worrisome start.....
