This "was" the wife's car (+I'm re-possessing it!). On the highway, started losing speed, coasted to the shoulder, called me...
By the time I got to her, the damage was done. One of the trans cooling lines had split- lost all fluid. It was cold, kids in car, engine running to keep them warm...now fluid runs straight through. A steady stream runs out the bottom, I'm assuming it's the main seal (yes, I repaired the original problem- split line).
I guess I'm hoping someone will jump in and say "No, you don't have to remove the entire cradle!"...and point out some e-z fix possibilities...
Anyhow, is there an easier way to get to the transmission main seal?
Should I drop the entire engine/drivetrain? Or is there a better approach to separate the engine/trans?
Is there another possible cause...maybe something else that would have trans fluid leaking out in the same exact spot (where bellhousing meets engine), and after being run at idle for 20mins without trans fluid?!?!?!?!?!?
So, I removed the "cradle", and blocked it up so it was easy to work on. I removed the transmission, and while the tranny was tipped as I was easing it out of the cradle, the torque converter falls of...AND THE TRANS SEAL COMES OFF WITH IT!!! It was riding on it's journal on the converter...the seal appears to be in good condition!
Should I assume that the leak was due to the seal having come out of it's seat? I've never had a trans seal, or any other seal, simply pop out.
Looking at the torque converter, the "bearing surface" (i.e., the interior of the opening on the torque converter that rides on the input shaft of the tranny) is marred. Not surprising considering the car sat idling without trans fluid, as mentioned above. I suppose I'll need to replace the converter... that bearing surface looks pretty bad...it overheated and "spun" a little. Is this in fact a bearing? The shaft is still smooth... Any thoughts?
