A clunk during automatic gear shifts can be caused by several factors, including worn or damaged transmission components, such as mounts or bushings, that fail to absorb the impact during shifting. Low Transmission Fluid levels or dirty fluid can also lead to harsh shifts. Additionally, problems with the transmission control module or issues with the engine mounts may contribute to the clunking sound. It's advisable to have the vehicle inspected by a professional to diagnose and address the underlying issue.
Worn trans or diff parts. If it gets worse, have it looked at.
A bearing that has gone bad. A universal joint that has worn out allows play in the differential gear.

That is one possibility for that complaint
low trans fluid level.
If it doesn't repeat the sound while the engine is running, especially accelarating or decellerating, it is probably related to the starter pinion gear or the flywheel/flexplate ring gear. When the starter gear engages the flywheel/flexplate, there is a small portion of gear tooth missing. It starts to catch and slips, slamming into the next gear and then engaging. Eventually, you'll lose another and yet another tooth, producing a dead spot to an extent the car won't start.
No, check the fluid level and have the transmission serviced. (filter and fluid replaced)
There are several things that can cause your 2005 Jeep manual transmission to shift hard between first and second gear. The most common cause is a malfunctioning shifting fork.
when the joint becomes worn, you can tell when it is warn as it will vibrate and a clunk sound will be heard when going in to gear.

Sounds like a vacum leak to me.
loud clunk when you put into gear usually means universal joint or joints are going bad, some labor involved but low cost.. u joints connect driveshaft ends to transmission and rear end
