I think a major problem has appeared
Every time i start the car, there is a check engine light on, when i drive it 1st gear works fine, 2nd gear feels as if there is no power going to the rear wheel but the rpm is still revving if you step more on the gas. Sometime(while in 2nd gear) the cars jerks as if it wants to rush really fast, it feels like the rear LSD is not in gear or something. After a few minutes of driving, the car all of a sudden has power and the check engine light goes off. It feels like something is not matching up with the transmission. Need more help....Again
Thank you
