I blew the trans cooler line off the RE46 in my truck, dumped 9 quarts of ATF+4 onto the road, and coasted into a parking lot. I fixed the line, filled it up with ATF and it functioned, but lost OD. I should have pulled the pan but didn't. I expected the trans was junk, so I just filled up and off I went. My trans doesn't have 200,000 + miles on it though.

Loosing the OD for you would be bad. I'd probably put in new solenoids and change the filter and try filling it up, might be OK.
