What kind of transmission did the Pontiac Bonneville have?
New for Pontiacs in 1965 was GM’s Turbo-Hydramatic 400 transmission, which was released the year prior. This new 3-speed unit had a torque converter, unlike the old fluid-coupling based Super-Hydramatic featured on past Bonneville models.
Is the 440 T4 Transmission compatible with the 4T60 transmission?
As far as mounts are concerned, the same transmission mounts that will work with the 440-T4/4T60 transmissions should also work with the 4T60-E transmission. But the 4T60-E transmission is a little longer on the passenger’s side than the non-electronic 440-T4/4T60 transmission is.
When did GM stop making the 4T60 transmission?
By the mid-1990s, the 4T60-E was the transmission of choice in nearly every front-wheel drive GM vehicle with the exception of compacts. A heavy-duty 4T60-E HD was produced only in 1996 for the supercharged GM 3800 engine. The 4T60-E was phased out in favor of the 4T65 beginning in 1997.
What was the neutral switch on the 4T60-E transmission?
Earlier versions of the 4T65-E transmission had an external gear position switch (which was part of the neutral safety switch that bolted onto the transmission under where the gear shift cable arm hooks up, just like the 4T60-E had). This switch tells the PCM what position the shifter is in.
The 4T60-E ceased production after 1999 model year. As far as mounts are concerned, the same transmission mounts that will work with the 440-T4/4T60 transmissions should also work with the 4T60-E transmission.

When did the 4T65-E transmission come out?
The 4T65-E was introduced to replace the 4T60-E in 1997. The 4T65-E included a larger 258 mm torque converter for some models and many other changes to improve reliability. It is able to handle vehicles up to 6500 lb (2948 kg) GVWR with up to 280 ft·lbf (380 N·m) of torque. A number of final drive ratios are available, with many distinct models.
