Cadillac SRX Transfer Case Noises

Are the popping noise coming from under the SRX keeping you up at night? Not sure what it is or how expensive its going to be to fix?

We hear that a lot around here. The Cadillac SRX came equipped with the Borg Warner 4476 Transfer Case. The transfer case sends some of the power produced by the transmission to the front wheels and the rest goes to the back wheels.

The original transfer case chain (CT-HV-080) was replaced with the CT-HV-095 chain. The 095 was developed for the Cadillac 265 and 295 equipped with the BW4479. Our understanding is both chains are the same in every manner except the 095 is a bit stronger.

The usual symptoms of a chain needing replacement is the sound of a popping noise under the vehicle when you speed up from a complete stop or the vehicle is under a big load.

If you would like to identify the transfer case model just go under the vehicle and locate the transfer case. Look for a white sticker or the casting marks on the case it self.

BMW X5 ATC-500 Transfer Case

The BMW X5 is on its third transfer case model. The first one was the New Venter 125, the second is the ATC500 and the latest one is the ATC700.

The NV125 is relatively a simple case to work on. It has three major bearings, three seals, a drive and driven sprocket, chain and other smaller parts.

The ATC500 on the other hand is a bit more complex. Unlike its predecessor it replaced the planetary gear with a clutch pack and contains a pump and a shift motor. This unit was introduced in late 2003; around October of '03.

If you are not sure which case you have you can simply go to the case and check for the transfer case shift motor. There are other exterior difference but this is the most obvious.

Internally you already know about the planet and clutch pack as well as the pump. You can also look at the chain. The chain has one blue link for the NV125 and two blue links for the ATC500.

The ATC-500 also has four instead of three major bearings and two plastic dust covers (the other having only one metal dust cover).

More information will be coming for the ATC700 as it comes in. Stay tuned!

Forks And Other Parts for the T45

The T-45 is a 5 speed rear wheel drive manual transmission used in Ford Mustangs. The case is aluminum and has a casting number of "T45" and is a three piece unit.

Unlike other standard transmission units where there could be several different possible kits depending on the size of bearing or other part the T45 is a bit simpler.

The differences in the kits appear to be by date. For both the Bearing, Gasket and Seal Kit with or without the Synchros the differences are from 1996 to 1998 and from 1999 to 2001.
