What year is the transfer case? 99-02 is the same, 03 up is different. Thanks

I'll check the tag in the AM aside case saver or aluminum case half and spline count between 4l80/4l60 what difference is there?
I'm under the impression they are all the same 99 & up.

The build date is 6-23-00 was put into service "as new not reman" in 2006 for 1999 & up applications.
The only difference aside spline count between 4L60 & 4L80 was later programming to "allow for more slippage" of clutch pack" I'm not sure if they ever included an aluminum half case in production.

The difference was the encoder motor. Pretty sure you can swap out the encoder and use it on a 03-07 classic. Starting in 07, NEW PROCESS went under and MAGMA took them over and started producing there own line of cases with aluminum housings instead of magnesium.

Like always Ferm "thanks for the heads up."
So the one I have is the early unit, no updated encoder motor.

 

[THEFERMANATOR]

It's not an updated encoder, just a different style. GM changed data coms in 03 which meant they changed controllers, and they also changed the actuators to go with the new controller. It was just a generational change, same thing happened with the 261/263 cases.

Good to know, thanks....

AutoTrac SOLD

Bump, I had forgotten the sale of the 1999 9.25 IFS w/ARB locker w/4.10 ratio fell through so its still for sale, it comes with complete manual, parts list, harness that has provision for controlling a rear ARB locker too, switches, and compressor however compressor needs seals and new exterior air lines.

NOTE: The axle seal issue was resolved and selling unit w/new extra seals included.
Asking $1k USD/FRN
I can't ship so it's pickup only in zip 34429

 

[FellowTraveler]

Open to offers on the 99 IFS 9.25" DIFF w/4.10 ratio & ARB AIR LOCKER however; because I have medical issues I can only perhaps do a small pallet w/straps so it an be shipped and have no shipping options available so if any of you decide you want it then you need to arrange for freight pickup at my AO.

 

[FellowTraveler]

Bump, looking to get $750. for this 99 IFS 9.25" differential w/ARB locker, harness, purge valve and compressor plus S&H.
