i have a 97 tahoe my trans went bad so i put in a used trans it shifts get but i noticed that if i get on the gas pedal i fell a vibration since i put the new trans in so does anyone have a idea that i can check and try[&:]

 

Check for things like the exhaust being against the frame or a bad rear mount. Somewhere your drive train isn't insulated from the body so your getting motor vibes.

 

You could have a part out of balance, but before you think about that, check your mounts and stuff as astroDzak said

 

Used tranny? Did it come from a reputable source?

 

well the trans that i put in was from a 96 forsome reason 97 trans were not the same as my 97 tahoe trans. but i noticed when i was tightening down the torque converter bolts the fly wheel was moving ininstead of the convertercomin out to meet theflywheelandyesthe transcame from a good place

now is it possible that a 96 trans is different from a 97 trans?does the torque converter on the 96 trans sit in further then the 97? or is it possible that the torque converter got stuck in to far?

Its possible that these things will get better as the tranny fluid circulates and the parts get used to you your engine vibrations.

 

ok when i was boltin down the converter bolts i noticed the flywheel pulling ininstead of the converter pulling to the flywheel could this be the problem? well it causea out of balance? and by the way sweet blazer digging the lights

 

Your bearings could be shot. There shouldnt be alot of end play from the flywheel.

 

well i found out the problem some how the converter got stuck in to far causeing the flywheel to warp when i tighted the converter bolts down.so i losend the bolts and pulled the converter to the flywheel and tighted the bolts.i never seen some thing like this before[&:]
