I have been on other forums can’t find any info to help me. I’m hoping someone has had a similar problem and can help. Okay so I bought a 92 f250 7.3. It has never shifted good from the day I picked it up so I ran threw the check list. TPS, tach, shift selonoid harness inspection and ohms test and selonoid pack test. I found the tps was way out of spec and old so I replaced that and tach sensor. TPS is set to 1.14 at ct and 4.3 at wot. Now is where the problem begins. At that setting the truck shifts at like 3500rpm from 1-2gear even higher into 3rd and I can’t makr it into od for fear of smoking the trans completely. Also every shift feels like a car crash. I’m seriously afraid the driveshaft is going to snap it shift so violently. If I set tps to .74v it shift around 2000rpm 1-2 and a bit higher into 3rd and od. But lugs just feels like crap and I won’t even try to pull a small trailer with it like this and is Still quite hard but not violent. Only code I have is 11. I believe that means all is good. Can anyone please help me to get this truck shifting properly. I have a rebuild kit for it but would like to save that for very last option and I would hate to rebuild and find I still have the same problem. Thanks
