Hello all, I am having a bit of trouble with my truck when under light throttle. Between 1000-1700rpm when driving with no load my 5.3L starts to surge about 50rpm with a increase in felt power when it happens. I am also hearing a vibration or light grinding sound. From my reading I’m thinking this could be a torque converter issue maybe the shift solenoid. When the truck is in tow mode I don’t notice the issue but if I leave grade braking on when the truck downshifts it does not feel normal or what I’m used to when I tow. It’s somewhat harsher. Thank you all for your time I sure appreciate everyone. Update: I just noticed when I go between Drive and Reverse it’s takes it a second to move then it jumps a little. Checked trans fluid looks good. -
So I was heading home from work and decided to fuel up with 91 octane and used the fuel system cleaner at the pump. Approximately 20 miles out of town my truck started to surge and the RPM's jumped on every surge. I thought it was the fuel until. The next day I stopped at a stop sign and when I eased my foot on the pedal the transmission acted like it was not engaged in 1st gear and then slammed into gear. I found a transmission at a wrecking yard but I'm not sure what caused this and am afraid the problem may still exist with a new tranny. Has anyone ever experienced anything close to this?
