Rebuilt E4OD slipping at 2-3 shift and TC locking up really hard sometimes
I've noticed since I've had my E4OD transmission rebuilt (in a 95 PSD E series Van) That the shifts flare once in a while and other times it'll actually slip quite a bit mostly on the 2-3 shift. And I mean BAD slips.
It's basically a slip from 2-3 --> RPM's shoot way up --> grabs for a second then starts slipping again and the process repeats for around 5 seconds until it finally grabs into third and holds.
The other thing I've noticed is that the transfer of the torque to the back wheels is not quite as good as it was before the rebuild. Things seem not as firm sort of like the engine is spinning but not having the grip that it used to before the rebuild.
The last thing I'm not happy about is that sometimes the TC lockup really slams. I think what is happening is the #4 gear and TC lockup are happening at the same time at around 45MPH which is really lugging the engine. The TC is never locked in 3rd gear even with OD off and at 45-50 MPH. I checked this by lightly pressing the brake pedal while driving (foot on the gas).
The WORST part about this is that it only happens sometimes so diagnosing may be sketchy (right now the van is back with the guy who rebuilt it). When it happens the OD OFF light will start blinking for around 30 seconds to a minute and then go back to normal (stops blinking). There's no real rhyme or reason to when it slips. It's happened cold and it's happened hot. Today I thought I was going to loose the transmission all together it was slipping quite a bit on the 2-3. One instance was probably around 20 seconds of slip grab slip grab slip grab before it continued on. The rebuild was $1785 and less than 150 miles old so this is not encouraging in the slightest.
Any ideas what could cause this and that it only happens sometimes?
EDIT: one other thing... when I floor it when passing up hill, shifts aren't firm (downshift to 3rd), it's as soft as can be.
