no TQ Conv Lock up

[Moremph]

alright went through a core tranny and put in a 95 (due to a cracked case in the origial) The core was believed to be a 96 or newer per the rough casting identifiers printed on the valvebodies indicating a 96 build year. The tranny was built and with a transgo tugger kit tuned to around 300hp and a rebuilt single disc suncoast convertor was installed

The convertor will not lockup on it's own or forced manually with a lockup switch.

The solenoid pack was acting goofy so i replaced that first with a known good 96+ pack Still no go i can here the pack clicking when the lock up switch is thrown but no lockup

Next thought rebuilt convertor was fubared... Replace that with a new HD single disc unit and still no lockup

Then i start investigating deeper, per the rough casting numbers on the new tranny case it is a 90 model case, I then pulled the valvebodies and verified this by comparing the worm tracks to my manuals it is indeed a 90 model (9 ball case) And when i recived it it had 96+ valve bodies (the pan was loose and had been off so who knows what they had done)

I reinstalled 1990 model valvebodies (and the 96 solenoid pack) and still no lockup, can here it click but no lock up


ANY IDEAS!!


Thanks Travis

I am by no means a trans expert, but it sounds like you are either 1) not getting oil to the solenoid or 2) there is a blockage/leak on the path to the TCC. The perverse thing is that a badly leaking passage/seal sometimes has the same symptoms and sounds as a blocked passage. Where to look, I don't know.

I would start with your case ID code. You have mismatched parts.
Do you still have your transgo install sheet? You will need it to id your parts. Case code,plate ID,gasket ID, VB code, Accm code, checkballs.

Case code E9 or FO?
