Not only were the splines of the transfer case input shaft stripped, the splines on the output shaft of the transmission were not in great shape either, so out came the transmission. Correction/Modification:Over the years, there have been instances of transmission output shaft splines being stripped off, affecting the transfer case input shaft or gear however, that scenario has been somewhat limited. The failure on the CTS must be a bit more common, since GM had issued a TSB concerning the problem under bulletin number 10-07-30-005A. A contributing factor to the shaft spline wear is lack of lubrication between the transmission and transfer case. Unlike other 4WD applications that use a pressurized or splash-lube system, the CTS basically runs dry, which can result in premature spline wear.To address this issue, GM has modified the transmission output shaft at the splined area ( Figure 1). The vehicle only had 71,000 miles on it and there were no issues up to that point.Something odd did occur when the shifter was placed into drive, and that was the speedometer started to register, and when the shifter was placed back into park a raking noise occurred, indicating that the output shaft was turning and the problem most likely was in the transfer case. Cause/Condition:The vehicle was put on a lift to see if anything was falling apart however, everything appeared to be intact. With the engine running and the vehicle up in the air, the noise could clearly be heard at the back of the transmission.

Once the vehicle showed up, the inspection process began to determine what the problem was.The CTS was equipped with a 3.6L engine and 6L50 six-speed automatic transmission. The vehicle was AWD, which meant dealing with more than just a potentially bad transmission. Is it possible with interruptThe owner of a 2010 Cadillac CTS started to notice a clicking sound when placing the transmission into drive or reverse.With the engine running, the transmission was placed into drive and reverse, but, as a customer indicated, there was no engagement. Due to a busy schedule, the owner chose to delay bringing the vehicle in for an inspection, until one morning that the transmission failed to make any noise. The noise was gone, replaced by a no-movement condition that brought the busy schedule to a screeching halt.Spline Dental Implant System proven to be stronger than external hex designs 1. Interdigitating projections and slots provide exceptionally precise fit 1. The spline set always has a V0 profile shift relation which means: x. If the splines are being designed, then one of the preferred pres-sure angles from the standards should be used. ANSI and DIN offer the choice between 30, 37.5.
