Ok so after i installed my rear AAL I got a lil bit of the take off shudder, so shims are on the way. After a week or so the tranny is downshifting really harshly when i let off the gas and sometimes while at a red light. It feels like the trans is stuck sometimes, especially after it downshifts. Its even stalled twice. I also have an URD MAF, but ive had that for a while now. At idle the RPMs are ~500-700 RPM. I had the pedal chop but cant say for certain if they did the trans flash, as they did the pedal chop while they did the rear leaf tsb. I also just installed a DDM HID kit, so they battery was unplugged but that was Monday morning.
Suggestions? I wana see if it goes away or if i can fix it before i go to the dealership.
