stock transmission

[Scott5586]

i was just curious on how much power can the stock auto trans handle. and do yall think i should put a stall and shift kit in it, it only has 17000 miles on the car.

stall the car and dont worry about it. the stock trannys hold power rather well. ive had a converter for almost 3 years and its been running just fine.
