Hey, guy sounds like the v-body was not rebuild correctly. You might want to purchase a new or use (if use make sure it was taken-off from a working tranny) they run form $95 to $140 for a used or $250 for a new one @ E-bay (Don’t know if you trust them). But I can hook you up with a buddy of mine here in El Paso, TX for around $75 or so just let me know, ok.
I was having a problem with my ST2001 Tranny back in Dec.2007 had to remove it myself and rebuild the whole thing (it was a nice experience). By the way I was a newbie to this Tranny rebuild stuff, yet my knowledge has expanded, thanks to this forum and other research I have done, by the way my ST is runny smooth and working perfectly.
Hey I also found out about a place down at Arizona that sells tranny (all types) around $950 (rebuild of course) plus the core fees (450). But you’ll get your money back once you return your tranny. Sounds like a deal!!!
Here are some prices:
T-Converter $95
Oil Filter $6
Gasket and seal $65 (all of them)
Servos ($12 Inter-Mid or $8 Overdrive)
Bands $18 Originals $9 Generic
Planet gear $85 (I had to change this one)
Shift Solenoids (al l4) are $27 each
Torque Converter Solenoids @ $55
EPC solenoid $94
V-body gaskets $4 each (u need two)
Clutch plates $4 each you need 14 (3 OD, 5 Inter-Mid, 6 Forward)
Tran-oil $2.97 @ Walmart
Vaseline $2
Then again I can get you the use V-body’s for $75 includes all parts except the gaskets.
