Transmissions problems again

Front pump seal blew out on me last weekend going down the interstate. I have something wrong with the trans (E4OD) which is causing it to go to 100% line pressure which in turn has blown out the front pump seal. I've called different places and had different quotes ($350-$850) for a front pump seal. The $350 sounds more like it. My CEL is not on and the OD light is not blinking so I'm thinking an OBD2 scanner will not pull the codes. I'm worried that it'll end up being ANOTHER full rebuild (first one came at 75K miles, I have 117k on it now). The shop that did the original rebuild bent me over pretty bad on the quality of their work. There has always been a ticking from the TC that they never would take responsibility for (always claimed it was the oil pump and not the TC). I'm thinking its about $1700 for a full rebuild on the transmission, sound about right?

Ticking in the converter? Sounds like the fins are loose to me, that is very common. As far as the pressure goes has anybody messed with the screw in the pressure solenoid?

No. It only goes to 100% line pressure (thats what I'm assuming) when the truck has warmed up. When the truck is cold, the transmission shifts fine, but when it is warmed up, it'll shift so hard that the truck jumps. I like firm shifts but when I'm in traffic, have little to no throttle applied, and the truck jumps and sounds like its about to break a ring & pinion, then I have a problem.

I'm going to pull the transmission pan this weekend before I take it anywhere. I changed my transmission fluid less than 7k miles ago, so there should be little to nothing in regards to metal shavings from the clutches. If its pretty clean, then I'll be pretty relieved that it probably wont need a rebuild. Hopefully I didnt burn up the pump when it got so low on fluid.
