1994 f350 with factory turbo and E4OD transmission. Previous owner had had it rebuilt. I had seen the receipts(i lost them though) and the transmission was very clean so i know he wasn't lying. I have finally started driving it after addressing other small driveablility issues. It has extremely harsh and late upshifts. 1-2 is shifting around 2700-2800rpm and banging. 2-3 shifts around 3000-3200rpm and is softer than the 1-2 shift. It varies. Sometimes it bangs a little, sometimes not. 3-4 is usually fine, however it wants to hunt for 3-4.
I installed a brand new tps, ntk TH0102. The truck was missing one when I got it. I adjusted it to spec and it didnt seem to help. I also checked the abs speed sensor in the differential, its good. I pulled the pan and accumulator valve body off to find that there was only one spring per accumulator. In the service manual they show at least two springs each and in most of the shift kits I've looked at use 3-4 springs. I read about someone who found that someone had put in the transgo HD tugger shift kit and that the calibration plate holes were drilled too large. So i have ordered the regular transgo shift kit and plan to install that.
What else should I check that could cause harsh upshifts while I wait for parts and have the pan off? I am very leary of the quality of this rebuild job. Among other things I had to add nearly 3 gallons of atf to it when I first got it. Makes me wonder how good of a job they did if they couldn't even be bothered to add fluid.
