I have 96 gt and i completely destroyed my old transmission and swapped a used one in...since then it vibrates when i accelerate....please help me whats going on? The tranny is the only thing i changed...is my driveshaft bent maybe when i removed it i wasnt too careful with it. Thanks
It's unlikely your driveshaft is bent, but it is quite possible that you didn't reinstall it the same way it came out. The factory driveshafts are not balanced all that well, and they need to be installed as indicated by marks on the driveshaft. If the driveshaft was installed out of phase, it will vibrate.
i worked today so i didnt get a chance to look at the car but tomorrow is for sure....i will also check and see if everything is tight and all the supports
so i checked everything out...rotated drive shaft and the u-joints.....still vibrates.....i also noticed that when i start up the car it vibrates right before it idles down....sounds like i might have bad tranny/torque convertor? even if its not in gear if i give it a lil gas before it comes back to idle it vibrates
Are the motor mounts and transmission mounts old/OEM? If they are original they are 14 years old and almost all V8 Mustangs are driven hard anyways, Urethane motor mounts from Energy Suspension made my car ride smoother and was very noticeable!
could they have mysteriously gone out as i swapped the tranny???? its getting real tough for me....i really dont want to take it to a shop.....since it really only started vibrating after i swapped trannies.....
