Well the rebuild did not fix the annoying overnight converter leak down. Guess I will just be continuing to live with that. Strange I don't recall my 64 Plymouth Sport Fury suffering from that back in the 60s and I don't recall the GTX leaking down when I first purchased it. Oh well.
I think the torque converter is growing on me. At 45 - 50 it kind of like having a part throttle kick down as the engine is a bunch more response when I first goose the throttle a little. I noticed at about one third to half throttle it runs out to about 4200 rpm before shifting into 3rd now - I'm wondering if it has enough more line pressure now to cause the governor to delay shifts until a higher rpm? I know the pump impeller I put in it had quite a bit closer tolerances than the one I pulled out and the shift kit should also increase pressures. With a stock cam and most everything else I don't really want to see more than a 5000 to 5100 rpm full throttle shift point I hope.
Doug - did you try to do anything on the Muncie on the front countershaft bore in the case? After a couple decades it seems like all of them wear there and start leaking. I have mine sealed to the bellhousing with RTV but it I tear into it I would like to find someone who can machine it out and install a bushing in it to tighten things up again.
There is a dedicated pressure regulator valve.I was just speculating that my old pump might not be putting out all it could. By regulator do you mean the throttle valve in the valve body or one of the other little shuttle valves in there. Guess I need to go read the book again.
Don't know what the deal is, with that. I've never had one leak down. Maybe I'm too stupid to know the dif! Hehe. Alway's thought the one valve in the shift body controlled that. Guess your saying it wants to slip, when you first get it going?Oh - converter still leaks down overnight.
It's possible, even with a shift body, and valves, that look good. Those valves are a very close fit, and doesn't take much to make them not work the way they should. There could be other issues that cause it, that I don't know about. Of course, 'modified' parts can play hell, too, if they are not spot on.I think maybe it must have to do with wear in a valve in the valve body.
