Title: QJet not going WOT
Post by: tayto on October 31, 2021, 11:12:15 AM
Have been fighting this issue since I got my truck running. WOT only goes about 75% with the gas pedal. I can roll the throttle to WOT with my hand. Have tried bending gas pedal where throttle cable hooks up, tried with and without floor mat, replaced throttle cable, tried with 1 or no return springs. Narrowed the problem down to the TV cable, with it disconnecting it goes almost to wot (let's say 95%). Transmission is a 700R4. Stock linkage, stock intake, carb is from this truck which originally had a 700R4, so bellcrank should be correct. Has new AC Delco TV cable and using Transgo's "updated" TV valve lineup. I think this is where the problem lies. I read an obscure post from Bowtie Overdrives from about 20 years ago saying that this is a know issue with Transgo's TV valve and Qjet's but offered no fix for it. Any ideas?

Have you ever dealt with Transgo tech support?
