Loud "clunk" when shifting out of Park

[kelvin]

mine will also "clunk" out of and into park. I'm pretty sure its always done it... i havn't had any problems with the transmission or anything like that. i allways assumed it to be normal. just dropping into gear....

when i had that same problem, i had my tranny fluid changed and it completely fixed the problem.

I just had my tranny fluid replaced 5K miles ago, and this problem started up shortly thereafter. Now i'm getting the "check engine" and "check trans" lights on my dash. I'm taking it back to the fluid changers tomorrow to see if it's been leaking or anything, then to the dealer. I'll let y'all know what results.

This sort of a general automatic tranny hint, but works especially well with the Isuzu 4X4 trucks:

When parking the truck don't move the gear selector directly to park before shutting down. Move the gear selector to neutral "N" for a brief moment, then on to park "P". In most cases you'll actually feel the torque converter and driveline unload when in neutral. This prevents the driveline from sitting under tension until you next use the vehicle, which is what typically causes the clunk when getting started.

When I got my first Trooper many years ago I would get startled when just sitting a light there would be a clunk noise and slight shift of the truck. I eventually learned this was the driveline unloading and perfectly normal. Ever since it's just been a part or being an Isuzu enthusiast. Except for the manual trannys, of course.

And the solution at hand as well!
