Please fill out the following to ask a question. MAKE: chevrolet MODEL: cavalier YEAR: 2004 MILES: 209000 ENGINE: 2,2 ecotech DESCRIBE ISSUE....suddenly lost reverse, 1st 3rd and 4th gears (auto trans) dtc set with codes p0756 p0730 p0530 u1000 u1064 and c 1275. now the u1000 and u1064 I suspect are from the oem radio not being present . c1275 is that the trac off has been requested by the ecm. the p0530 is a/c related (it doesn't work). p0530 is a kinda generic code for incorrect gear ratio which leaves the biggie..p0756 shift solenoid "b" performance or stuck off. had a local shop put her on the rack and check the fluid..level and quality appears fine. When they went to pull it out....found the trans is locked in reverse and neutral....had to drag her out of the bay. car drives in second only. Any ideas?
