Trans. slipping in reverse?
I have a '99F350 w/ AT. Trans seems to be slipping when I backup with a trailer hooked up. I haven't noticed any slipping in any forward gears. Fluid level is good and smells and taste ok also. 100,000 miles, filter was changed at 50,000. Would this be a valve or something more drastic?

I have the "clunk" when going from a stop. My problem in reverse may be a little different because the transmision seems to engage but I dont have any power until the accelerator is depressed a quarter to half way down. Very noticable when backing a heavy trailer, but also noticable when the engine is warm and backing. Could this be the same issue with the slip joints?

Would reverse clutchs be different than the others? I thought gearing, valves, etc. would make it go backwards, different clutch pack, that I don't know! Thats why I got on here and was asking. Thanks again.

reverse gear is not as low geared as 1rst gear..its a little harder on the clutches..when ever i back up a big load i always put it in 4x4 low..takes a lot less peddle to get it moving.for you at this point it might be worth changing the flued and filter...
