tranny problem ... real headache

[mdkallam130]

i have a 2002 f250 with a recently rebuilt 4r100. it was rebuilt back in march of 08.

here is my problem: when i take off in drive its like its taking off in a high gear until it gets to about 5 or 10 mph and then everything shifts fine. i can take off good by switching from 1 to 2 to drive manually. it only lacks in power when i try to take off in drive.

im thinking it might be a relay or maybe a blown fuse but im not sure.

the transmission shop that rebuilt it keeps telling me its something electrical and not mechanical. it throw a code for overheating but the temp. gauge stays within normal operating temperature. even on 90 degree days i never see over 180 degrees.

if any techs have any idea.. please help... this thing is really giving me a headache.

Just guessing here,but I would say it is a bad shift solenoid.The solenoid packs probably took a crap.There around $250 for actual ford ones and less then that for non ford ones.Mine did the same thing in my 99.I kept driving it and mine kept overheating and after a couple days,it smoked the clutchs but the tranny had 258,000 on it so the clutchs were not in the best condition anyway.I would not drive it till you get it fixed so you don't mess up that frsh tranny.Oh ,and I forgot to mention its real easy to change the solenoid packs in there.Just drop the pan and its right there.It unplugs from the Passenger side of the tranny on the outside.
