Hello everyone i am new to this site but have a few questions and hope to get a few answers well here i go I have tranny problems and as i have read the threads i not the only one I have a 2000 ls that has been nothing but a pain in my ass from new engine to now tranny problems. This is the problem my ls tends to shift very crazy and just the other day when i got on the freeway i punched it and the f**ker cut out after the tranny acted like it slipped and rpm went way up to about seven thousand pulled the car over and started it back up and it was fine. The later on in the week it did it again but not all the time. It also shifts in reverse real hard or delay when put in drive. Can this be the solenoid and valve body or do i need a new tranny and how much would the solenoid and valve body be to fix. NEED HELP THIS CAR IS COSTING ME AN ARM AND LEG. :L
