CJ5 Torque converter bad? TF904 964?
Happy Thanksgiving! Apologize for length of post- covering bases.
1982 CJ5 w/ 304 (yes, I know no factory option 304 in 1982 - motor swap two owners ago) orig had I4. Driving to Turkey dinner on I-35 at 65 mph the engine raced - immediately no transfer of any power to transmission or wheels. No noise of any kind (gears, bell housing, t-case disintegrating, etc) Slid shifter to Neutral and coasted to stop. Initial inspection hand tested for excessive heat on power train components - nothing hot - had only traveled about 5 miles from home. Underneath saw blowback oil from rusted through dip stick tube wetted back of block, bell housing and probably torque converter/flywheel. Also some t-fluid on bottom cover plate but level on dipstick (engine running)showed about same as last check three weeks ago. Tried all combinations of shifter w/2WD4WD fwd, rev - nada, zip, nothing. High rpms needed to shift regularly - Holley/Edelbrock intake - previous owner motorhead.
1.Does this sound like converter failure or at least slippage caused by oil blowback?
2.Or tranny rebuild?
3.Bell housing has “964-3" cast on each side - is this a 3rd party # related to TF904? Could not find TF 964 model. Also stamped “85" near t-case end so probably was rebuild/replace at some point.
4. Is this a DIY? Have lots of tools.
