Transmission... hesitation?

So pretty much everytime I am at a full stop and then get on the gas( either hard or soft) I feel a hesitation where it waits a second and then you feel like a bump. You can sometimes creep off the line but once you get into it a hair you will feel that bump. Shifts fine. I also have a slight hesitation when going into the gear (park to reverse or any combination) and am wondering if all this is signs the tranny is going. I have a receipt from p.o saying they put a new converter and did something with 2nd and 3rd less than 1000 miles ago. What do you guys think? I need this truck for pulling my trailer daily and also plowing and want to make sure I take precautionary action if need be. Thanks

My 01 did that, best way to describe it is it was hanging in 2nd then would drop into 1st when taking off, what does it do if you tap the throttle while holding the brake before taking off? this seemed to get it to drop into low and take off fine.

I rebuilt it last year, and did find a broken spring in the valve body that could have been the problem.

I just bought an 01 that does this as well.
I am very interested in what you find.
I only have 80k miles.

the slight hesitation going into gear could be from the shifter cable being out of adjustment.

also trans go shift kits will cause a monetary pause before going into gear.

from what you describe your slip joint needs to be greased. unhook the rear driveshaft from the rear axle. take the boot off and pull the driveshaft apart. put a little grease on the splines and reinstall everything the same way it came off.

So....I had the transmission flushed and filter changed last week. On Saturday, I noticed a large spot on the driveway. I was transmission fluid. I took it in this morning and my mechanic says the front seal is leaking and they will have to drop the tranny to see if the torque converter has a groove in it.
He said this is a common problem with this tranny??? Any comments would be appreciated.
Mileage: ~80,000

I don't think its super common. I think the front seal usually goes bad from extreme atf temps

Been thinking the same about the trans temps. I bought the truck from my Aunt with 78k miles on it. I bet 60k was towing a 40' travel trailer.
Thanks again Blue.

sounds like its time for an upgraded transmission cooler.

check out the tru cool from dieselsite or fit a 6.0 cooler instead. both are better than the dinky stock cooler.
