@psrivats, welcome back! I ended up fixing my locker switch dilemma you were helping me with last spring. I went out and blew up my rear LSD, which took out my gears and Rubi locker in the rear. New ARB and associated switches took care of that!

Ouch! Sorry to hear that. Impossible to find stock replacements and ARBs are very good from what I hear. The switch setup is a nice bonus :) Hopefully they will serve you well for a long time.

My rebuilt transmission went in late last week (ATS diesel with upgraded valve body and their torque converter). The torque converter shudder that I felt on the old trans is not present here at all. The jeep feels so smooth to drive at hwy speeds now and the difference is very perceptible. It is amazing how much we take for "normal" on our used vehicles as we get used to them. I was quite frustrated this summer with the shudder on long trips and I could feel it slowly getting worse. Even my non-jeeper/non-car-enthusiast friends that traveled with me could feel and hear it. I am so glad that this is resolved now.

With the rebuilt trans, the upshifts feel really smooth and normal but downshifts feel quite firm (esp the 2-1 downshift) esp after you first start the vehicle and start driving. It does get better after the vehicle has been driven for a while. The shop that did the install is very well versed with properly checking the fluid levels on Chrysler transmissions and such so I have full confidence that the install was done correctly. I had a chat with ATS diesel tech support and I am told this will get better after a couple hundred miles (adaptives were reset post install). Will update here as to what happens.

@NashvilleTJ @Grover728 did you guys experience anything similar with your rebuilt transmissions?

@Chris for your records since you had asked me to let you know how this turns out :)

What do you mean by a firm 2-1 downshift? When shifting manually?

I wouldn't worry but if they did the transgo kit it's just a side effect of the system pressure change (I think a new spring) and the accumulator bleed change (one of the holes they drill). People that want high performance want short shifts and that's part of what those two things do.

I can chirp 1->2 sometimes when playing around but 2->1 has been smooth. I wish I had replaced the torque converter long ago.

The TC is the main reason why I went with them. Hoping that it is all they say it is and lasts a good while without issues 😂

Never had that issue as I recall.
Did you get their valve body or kept the stock one?

Thanks, that kind of makes sense. Not sure if they use transgo, but they indeed do some mods to the valve body to increase the line pressure (see website blurb below). They said it would get better after a couple hundred miles. I will update here as to what happens. It is nothing harsh or anything, but distinctly different from stock and impossible to miss/
