Last week I changed my old motor mounts and now on occasion when I accelerate there is a hesitation for a few seconds until it catches. Sometimes accompanied by a clunk that can be felt. Is this a tranny problem or could things be out of alignment because of the new mounts?

Sounds like you bought bad mounts to me

its definatly not the mounts, they are Ironman 4x4 and they keep the motor in place. My old mounts were so shot that my fan clutch went through my radiator so I'm thinking the old mounts may have caused some problem.

Did you do the trans mount too?

I did it close to a year ago, but I'll check it tomorrow to make sure.

when you say hesitation, is it RPM not climbing or what? you probably knocked something loose while climbing around on the engine. I would check the TV cable, trans plug, vacuum to the map sensor, stuff like that.

clunk could be anything, bad u-joint or something.

Sorry for the bad description. The RPM's rise, but there is no acceleration.

Figured out the problem. I also had a new radiator put in when the motor mounts were done and the joker who did the radiator didn't properly tighten the tyranny line so I was slowly leaking fluid.
