Pinout?

[lesterl]

1997 Venture 4T60e, I dont have 3rd gear on my rig. Manually shifting into 3rd only nets 2nd gear. The trans will shift from 2nd @ 5k to 4th @ 2k RPM if you are trying to get on the highway. If in town and under 40 MPH it will stay in 2nd. If you get above 45 it will drop into OD.

Question, does anyone have a pinout on the transmission? I want to meter the solenoids for continuity before I tear into the thing. I suspect (hope it isnt) that the 3rd gear clutch pack is toast. The Trans was run low on fluid a time or two (low not out.) I changed the filter and fluid and it didnt look horrible (was dark and alot of grey slimey stuff in the bottom - this was after a can of cleaner/ seal conditioner was added)

Any Ideas? Any Wiring diagrams specific to the transmission? It may be a while before I get to tear into the thing, so stay with me I WILL post back what I find.... Thanks for looking/ helping. :-)

Is there a CKP relearn that needs to be done on these motors when swapping motors?

I am running (per 2 of my scantools - new one and old one) in the -30 range on Ign timing. Ideas? Newer motor in my 97, has 00 stamped on the front valve cover. Had to swap over alot of crap off the front of the motor when swapping.
