My 96 EB Bronco, 5.0, 102K miles has developed transmission shudder when I start up after a light. Fluid is changed often and is Mercon V. Also has a slight clunk when I stop, then give it some gas. Drivetrain is new - universals, upper and lower balljoints, new traklok rear axle so I suspect tranny or engine mounts.

Anyone have any experience with tranny shudder and slight clunk that is not a universal or rear end issue?

Even the best-maintained slushbox will eventually wear out, so take it to a pro for diagnosis.

Regardless of what parts have been changed, the most likely causes of a clunk are 1) U-joints, 2) rear pinion nut, 3) frame noise, $ 4) normal slop in the t-case & rear diff. The engine/trans mounts are padded with rubber, so they don't usually make noise even when they're bad. They just allow the fan to hit the shroud. So always start by rechecking any recent work (or take it back to the shop & let them recheck their own work) and then examining the driveshaft.

To diagnose frame noise, click my black Bronco in my signature, scroll to the bottom of the list, & read the captions in the Frame Noise TSB album.

Steve -- thanks for the info. I suspect the problem may be slop in the spline on the tranny tail shaft. Checked the steering and Ujoints yesterday and they are OK. May also be pinion noise from my new traklok rear so its going back to the shop for a look.

Nice job on your 83 rebuild and website pics.
