2004r issues.

[Awann99]

I just finished up my 2004r swap. I was driving down the road and started to smell tranny fluid burning and the transmission started making a slight grinding/slipping noise. I pulled over immediately and it seems that my AUX transmission cooler line had popped off somehow and fluid was just pouring out. My question is, do you guys think the transmission is fine. Or should I pull it and swap back to my th350 until I can get it rebuilt? I don’t really want to chance the truck breaking down on me if I am farther from home. Thanks.

I would fix the hose and fill it with trans fluid. That is the only way to know if it is still good (or at least serviceable). I think if you pulled over right away it should be OK.

Cj is right filler up and test drive it....it's probably ok.

Got it filled up and drove it home the rest of the way. Seemed to shift and sound fine. All the fluid that spilled out didn’t smell or look burnt. Thank you guys for responding.

You're probably fine. Just be sure the geometry on the kickdown is right. I know for a fact a 700r4 will slip if it's not right. The specs are out there as far as radius from the throttle shaft, etc.
