95 E4OD NO Lock up

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 never saw a hp setting in there.

The E4od is an electronically controlled transmission, but the control still depends on mechanical parts and sealing. The click you hear should be the actuator moving. Ohm the pack anyway. Check your shaft seal. Then check your pump valves and halves for more mixed parts. There are many mix-ups like that out there disguised as cores.

Unless the case was dropped or lube starved, the tranny isn't the cause of the crack. It's the victim. Check your driveline for bind ups elsewhere.
