Ok so this is the issue I am facing, I have the p1811 code, max adapt, long shift, 2001 Pontiac Grand Prix GT, 151000kms. All the shops in town tell me I need a rebuild. One shop said they'd install an oversized valave body for $400 and that would solve it but I don't think so. Some shops say $1900-2400 with 1 year 20,000kms warranty, other say $2000-3000 with 2 year 40,000kms warranty. I want to know if my car is worth this repair bill, should I drive it until it break then repair or sell it while I can?

Other issues i've noticed are that the steering wheel is slightly crooked when the tires are straight, the accelerator pedal is pretty stiff and the car burn about a litre or quart of oil between oil changes.
