New Trans slips when shifting!

[SeEKandDESTROY2]

Just picked up a 1996 F350 Powerstroke. New Transmission and Computer 6 months ago, with receipts. After driving for about half an hour, sometimes starts doing it when its cold, regardless it seems to slip very bad when shifting between gears.

I normally let of the gas pedal, and wait for it to shift and then ease back on it. Getting it past 35mph is a white knuckle ride. Going to take it into the transmission shop who did the transmission and see what they can do even though the warranty is up.

Anyways, any ideas? Thanks, Pete

i have the same problem with 2nd to 3rd its like the convertor locks in second and has to unlock to shift. im puzzled

Same for me, slips bad in first second and third but gets better after five or ten miles. Still slips after that just not as much. From what i've heard it's a common complaint but no one seems to have a solution. Gotta be a converter issue because I've never heard of it happening in fourth once it locks up. Let us know what the tranny shop says

I'd say something is wrong in there for sure.

Make sure the fluid is at least 1/2 inch above the full mark. The dipsticks were too long on all the early to mid '90's.

Would my '97 have the long dip stick, didn't know if it was considered mid or late 90's thanks

Don't know exacntly what date they fixed that problem but I put trans fluids at least 1/4 above the full and all ford e40d'4r100 at least 1/2 inch above, even '03.
