Question

If I replace and engine in my car will i have to replace the transmission??

Answer 1

No.  But there is factors  involved how many miles is on the tranny and why is the engine being replaced.  Did the tranny still shift ok?  If i were to replace the engine i would change all of the tranny fluid that means train the torque converter also.  Maybe even an over haul kit 80-150 bucks.  But it depends.  If it shifted fine then just change the fluid and filter on the tranny.

Answer 2

no, not typically .. however if you have abused your motor, chances are good you will have to replace your transmission soon... good luck,jim

Answer 3

No but if it's not in the best of shape now's the time to do it. It's often easier to remove the engine and transmission together.  

Answer 4

Assuming you are replacing the engine with the same engine (ie GM 3800 with a GM 3800) then no.  If you are changing to a different motor than the one you are removing then you will have to check for compatibility.  Some motor/tranny combo's do not work together. Hope that helps  =)
