SOURCE: transmission downshifts hard when I let off the gas at slow speeds

Transmission sensor.your gear ratio was not set up properly..Its supposed to be mapped out soo the tranny shifts at a neutral rpm(around 2500-3400 rpm) its punching into gear correct?could have been a rebuilt tranny in which case they just replace the current problem..Or it could be a flywheel.1st thing to get done is to change the transmission fluid and filter.Goto midas or somewhere like they and they call it a flush and fill and it costs around $160 which is best case scenario.

Can I put a 1994 Caprice 350 engine into a 1990 GMC 3/4 ton truck ?


yes but it will be difficult. a wiring harness swap will probably be needed since 93-94 were the experimental years for computers. you may need to swap trannys also. i advis you to have fun, the 5.7L chevy is one hell of a hot engine :) its the same one used in corvettes and comaros.
