Well, the SS is wearing out faster than I expected since I have been babying it for the past year.
I replaced my front bearings and I still have a the bump bump crank crank pop pop pop feel and sound from under my seat and the drive selector when turning left and giving it gas. My last item to replace is the CV axles to fix the problem, any other ideas on what that could be?.
Recently, the car (under slow acceleration has been having issues at the 50MPH shift into 3rd at 1500rpm. the engine sounds like it chokes out and the tech jumps up and down 200rpm. Exactly like when you drive stick shift and release the clutch too fast and the vehicle jerks for a sec. or two and smooths out. The car does exactly that. Any higher in the rpm and the car does not do this. Three things come into my mind, shift solenoid going out, clutch going out, spark plugs fouled because its under a load. Or a wild hair is the PCM. Suggestions, ideas?
If I cannot fix the tranny issue under $1200 I'm selling the car, the fuel pump, bcm, ignition cylinder, and bearings crapped out all at once and drained my bank account.

Thanks for advice and suggestions!!

Man that sux...whats your location? Here is a long shot...the trans depends on the TPS to tell it how to shift ect...if you have a multimeter...unplug the TPS...I don' remember offhand which connectors to hold the leads on, but see if you have a flat spot in the tps, or a dead spot @ low throttle.

Are there any codes? I am not sure if the fuel pressure regulator has much to do with the jerking but I have read that the FPR makes all kind of weird things happen, but what 98SS said makes sense also. The TPS is real easy to change and cheap to get.
The clicking sound can be the steering shaft, can you feel it in the steering wheel when you turn? Have you tried doing a retorque on the engine cradle? Im trying to help you keep your SS

I appreciate all your advice, I'll start looking down those routes. I came up with no codes when I plugged it in. I re torqued my cradle and they were tight to begin with, the most recent ISS, #4 that got replaced is the the wrong ISS because it makes makes a bouncing/loose noise like it is physically sliding or hitting its ends when going over speed bumbs. All other ISS 's did not make that noise or were loose. The only item left I have not replaced in the car, minus the engine, tranny, and rims is the CV's which is why that is next.

Also another issue I have seen in the past on other cars is the rack & pinion to cradle bolts, they are 18mm on both sides. For some reason I thought you replaced the axels, but those will give you a pretty loud clicking noise usualy when turning but if they are bad enough it will do it when accelerating. Is the front end tight, tie rods and ball joints, control arm bushings? Those will also make noises when bad or broken.

Fix what you know is broke first, then it may be easier to track down the other problem if there is one.
