Hi all!
So I loaded the pathy up with gear and the girlfriend and headed towards the hills tonight. After about 20 minutes of doing 75 on the freeway, we heard a very audible clunk, and pulled over to the side of the freeway. Transmission fluid was everywhere on the passenger side of the engine bay, looked like it spewed forth out of the transmission fill/check line. I wasn't able to find any lines disconnected or burst, and could find no active leak with the truck running and it being ran through the gears. We then limped to a rest stop and I checked the fluid level. It still read "full" for hot, and when I went to check the level I noticed the plug/dip stick being loose. Thinking it might have been a freak occurrence, we had dinner and got ready to continue on. That is until I put the transmission in reverse only to have the engine die.
It still drove in "D" although it seemed to require a lot more revs to start from a stop. We pushed it out of the parking spot and set to head back home. Getting on the freeway I was running with my harzards, doing a max of about 45mph. Anything higher than that and it would seem to disconnect and just rev before settling back into gear. We are now home safe, and I tried reversing again when I got here. The engine stayed running but reverse did not engage.
Is my transmission screwed? I just did a fluid flush + additional filter + bypassed the stock cooler for a new 18000 GVW unit about 80 miles ago. It had been acting just fine around town. The tranny is the original and has about 198K miles on it.
I'm having bourbon and beer now, and we'll be repacking the girls car to head up tomorrow, but I wanted to pick your brains on this one.
