Hi everyone Im new to this site but I've read a lot from it.
I've got a 2000 f250 with 136k. Itís been babied its entire life minus having 38Ē tires. Anyway I was driving it New Yearís with an empty trailer and OD
off when I noticed the OD
light flashing. NOTE: I did not have a transmission temp gauge (I do now). I immediately pulled over. I had transmission fluid pouring out from the bellhousing. I let it cool, put 7 quarts of mercon V in it and drove it on a trailer to get it home. The first thing I did was drop the pan. The pan looked nice and clean minus a little sludge on the magnet and the fluid being dark. Transmission was flushed 40k miles ago by ford. I then started Marks Transmission Flush procedure. Right off the bat I had transmission fluid spraying out of the return side of the transmission (not the return hose). At that point I found that my cooler lines where completely clogged and the bypass tube was working. The bypassing/spraying would only happen when the transmission was in gear, not park or neutral. I blew out the cooler lines with compressed air and replaced the 7.3 OTA
cooler with the 6.0 cooler. I performed a flow test on the return line and it filled a quart bottle in 15 seconds. I then took it for a drive. 15-20 minutes into my drive I noticed the temp coming up on my obd2 scanner/gauge (230F). I made it home and found my OTW
cooler completely clogged. At this point I just wanted my truck back so I bypassed my radiator cooler and just ran the 6.0 cooler. Transmission shifted into all gears nice and smooth,and the temperature never got above 177 BUT in both 3rd and 4th it randomly lock and unlock the TC
a few times.
Obviously there is something clogging the lines which at this point I think is my TC
coming apart. What should my next step be? Replace the TC
and keep my fingers crossed that the rest is fine, save up for a new tranny and not waste any more time or money on this one, install a inline tranny filter and ride this one until it blow, etc? At this point Iím looking for some advice/guidance. Sorry for the long story.
