Torque arm poly bushing and trans poly bushing

I just replaced my torque arm bushing and trans bushing, my car is a 98 with 63,000 miles. My shifter was jumping up when I accelerated so I replaced both. Now I feel some vibration, is this because everthing is so tight? When I hit the gas it does feel alot better with quicker throttle response because there is no flexing up and down with the arm. I did set a jack under the transmission so nothing changed. Is this normal?

If you used ES poly you made a mistake and it won't get any better. Prothane makes a MUCH better poly tranny mount.

That sounds like a poly mount. Poly is much harder than rubber, so that's why you feel the vibration. After a while, you will get used to it.

Sorry, but not true.

With the ES poly trans mount if you grind the 2 preload bumps flat, there's very little vibration at all. And as far as Prothane making a better trans mount, I really can't say since I've had a ES trans mount on my car for over +6 years with no problems.

Thanks guys seems to be better now after a few drives, I think it was just to tight and needed to be broken in. But ya the stock rubber was a lot softer and dry rotting.

My experience with ES has been horrible. To the point of the mount breaking completely (picture) and then after I replaced it with another the next one was so stiff and harsh I couldn't do it. Hell it might as well have been solid! Prothane was 100% improvement over the ES.
