Problem with Transmission after Gear and Axle Swap.

Hello, I have a problem. I just had an Aussie Locker installed in the Front Axle of my 1999 TJ Wrangler and a Detroit in the Rear along with a Super Dana 35 Axle Upgrade. I also had my 3.73 Gears replaced with 4.56 Gears. I plan on changing my Tire Size from 32 to 33 but haven’t done it yet. After the work was completed, now I’ve noticed that its harder to shift with the Transmission Grinding between Gear Changes. The Detroit causes some terrible street characteristics that I may have to get used to, however, what could cause the Transmission from Shifting properly just from these upgrades?

You spelled it yourself. It is the detroit in the rear axle. The adjustment to fix the problem starts with you slowing down your shifts. Also find the proper RPMs. Then you're golden.

Yea, I'm starting to understand that. I'm starting to think that I would have been better off with the Aussie in the Rear instead of the Detroit, but I wanted to upgrade my Axles and Aussie didn't make a Locker to fit the Supper Dana 35 Axles. I didn't think the Detroit would be so difficult on the street. I'm trying to get used to it.
