Hey guys recently got motor and suspension rebuilt in my old original 2.3 car it now has a built 8.8 rear end new rear and front suspension and a v8 runnin about 300+ hp in it question is about the transmission. I believe this car still has the original T5 tranny that came with the car I know it still had the original 7.5 axle under the rear until i replaced it a few weeks ago been having trouble with the transmission grinding really bad and its very stubborn at changing gears especially under hard accelleration. Can the 4 cyl trannys be rebuilt to withstand the new motor or do i pretty much just need to drop the bread on a rebuilt WC T5? I been getting mixed reviews around town about it some say I can rebuild the old tranny and others have just told me to find one out of a original v8 car. Any ideas??
