September 2000 Issue

Issue Summary:

Some overdrive planetary gearset changes that were made in 1995 Chrysler A518 models can create service concerns. We have covered those changes from the previous-design straight-cut (spur) gears to the 15° helical-cut gears.

In the middle of the 1997 model year, GM changed the transaxle case, channel plate and check-ball locations on the THM 4T40-E. Those changes are noted along with the illustrations.
