Do you have a low mileage transmission for a 1999 4x4 Chevy Silverado with a 5.3 motor.

No sorry , however if you or anyone you know happens to be looking for a 93 standard cab silverado runs great , looks ok . actually i think this trans will work for you it is a C400 with is good from 93 to 99 I believe, but I have to sell the hole truck Or A 65 mustang convertible , solid body and frame no motor , all original parts .for a restoration Or A 94 f150 for parts , 5.0 motor and trans to go with it . no bed . motor and trans are good,

Have to call them directly
