Ticking sound and no power from a stop.. HELP NEEDED

[Mack 1996 xj]

Hey,
So I have a 1996 Xj its automatic and have been trying to find this issue with no luck. It has almost no power from a stop when the transmission is in D. When I put it into 1st and 2nd from a stop it drives just fine though. So basically I can manually shift through all the gears by hand, but it will not shift itself from a stop.

Also their is a loud ticking noise under acceleration. Ticks like crazy and sounds like parts or metal. I replaced my tps and that did nothing. All my sensors are pretty new and I dont see how they would be effecting the transmission. I will be checking torque converter bolts this weekend, which was suggested by another. Could it also be a shot tcm ?
Anyone ever had this issue any help is needed.

If you can shift all the gears 1-2-3 manually, the transmission is probably good, and the TCM or TCM wiring is suspect. Start with cleaning and snugging the TCM ground at the oil dipstick tube.

What is ticking, exhaust manifold leak, u-joint, double cardan joint, disk brake dust shield, torque converter bolts ? The TCM does not tick.

Tick sounds can be many things. I don't want to bring bad luck. Mine sounded like a lifter. Sounded like one in the front. I only heard it from the front driver side. My piston skirt eventually came off. I did check my flywheel bolts. A neighbor got a good deal on a ZJ, with loose flywheel bolt. Also, possibly belt

Could be shift solenoids also. If both #1 and #2 solenoids are bad, you'll be stuck in 4th unless you manually shift. If #1 is bad, you'll be limited to 3rd and 4th. On the other hand, I would not expect both solenoids to go at the same time so Tims recommendation of looking at TCM/wiring first makes sense.
