Most 1996 Grand Cherokees had an automatic transmission. Manual options were hard to find, especially in the U. S.
Automatic Transmission Details
The 42RE and 44RE are both 4-speed automatic transmissions. Here’s a quick comparison:

These transmissions were known for their smooth shifting, but needed regular care.
Manual Transmission: Ax15
If you find a 1996 Grand Cherokee with a manual, it’s likely the AX15. This is a 5-speed manual transmission.
- Seen mostly in older or base models.
- Offers more driver control.
- Good for off-roading and towing.
However, most buyers chose the automatic for comfort.
Transmission Fluid: What You Need To Know
Using the correct transmission fluid is very important for a long-lasting transmission.
- For 42RE/44RE, use ATF+3 or ATF+4 automatic transmission fluid.
- AX15 manual uses 75W-90 gear oil.
Always check your owner’s manual to confirm fluid type.
How often to change? Jeep recommends changing automatic transmission fluid every 30,000 miles for normal use. For heavy towing or off-road, change it sooner.
