"check sync state found it was off by 14 degrees reset to 0 test drove engine performance normal lot of truck for the engine to pull"
ok, im crying foul here! the truck is nowhere near its GVWR. it did run better, but it wouldnt run 65 MPH in overdrive. to get it to run even now it requires taking the truck out of overdrive. the truck does run better than i did after calibrating the computer to the engine, but theres NO excuse for it to not run 65 in overdrive on the highway. while i know the 3.54 suck and regearing to 4.10 will fix most of this, i still dont believe im getting the power i should.
fast forward, in addition to running weak i had also taken it in for the unit bucking on acceleration almost like it was cutting out. they couldnt find a problem initially. when it did it again on the way home i turned around and took it back. at that point they replaced:
transducer and solenoid, 96618 CDR
56028196ad transdue-pressure sensor 4617210 solenoid-transmission governor 52118789 filter-valve body 5 patf a.t.f 2464324ac gasket-oil panthat was another $622 and the bucking did go away, but the truck still wouldnt run 65 mph in overdrive. dealership claims its just too heavy. i put the truck on a trailer and pulled it with another truck with the same engine, tranny, and gear ratio and had no problem running 65 in overdrive. dealership has no explanation.
it was feb 21 when i took it in to the dealership to fix the bucking in the tranny, and on the 28th i get a "tranny temp" warning light. i took it to the dealer today and they say nothing is wrong with the tranny. they recommend i put the tranny cooler in front of the condenser. i asked them why it never over heated in all this time and now it needs an additional cooler and they have no explanation. they insist nothign is wrong, but the truck didnt get a tranny temp warning when pulling a heavy trailer in the middle of summer so why would it be overheating now in sub-freezing temperatures while not pulling a heavy trailer? they suggested it was just a freak thing that happened. i leave the dealership and get 10 miles up the road and i get another "tranny temp" warning. they want me to bring it back in the morning.
at this point im about to blow a head gasket on my brain. any suggestions appreciated. i keep sinking money hand over fist into this truck with all of 75,000 miles on the odometer and still nothing is getting fixed. thanks,
