O.K. - Have removed the tranny - BTW-It's an 4R100 - not E40D like I originally thought.

Mechanics EARN their money.

Dropped it off at a local rebuilder who is going to have a look beginning Mon. (bigger shop said around $2,000) Ouch! That's with the "friend" discount as the manager is a neighbor.

Need to source a new cooler. I'm hoping the rebuilder will replace the TC.

 

Usually its part of a rebuild to either exchange or flush the TC. You don't have to replace the cooler, just flush it out good.

 

Oh boy, she be toast!
Even the case needs replacing!
Here's a few pics...

 

With this much damage... I think I'll go ahead & replace the cooler after flushing out the lines. The rebuilder will be replacing / repairing the TC.

 

T'is a fine job ye did!
