1995 Jeep Grand Cherokee transmissions from that era typically fall into two categories, each with distinct strengths. Understanding your 1995 Jeep Grand Cherokee transmission is key to keeping this classic SUV on the road, whether you’re dealing with the popular 4.0L inline-six or the torquey 5.2L V8. This guide breaks down everything you need to know about the transmissions available, common issues, maintenance tips, and upgrade options.
First off, let’s get the basics straight. The 1995 model year was a transitional time for Jeep. You got the updated interior and exterior styling of the second generation, but the drivetrain still had roots in the earlier ZJ platform. The transmission you have depends entirely on which engine your Grand Cherokee came with.
1995 Jeep Grand Cherokee Transmission Options
There were two main automatic transmissions used in the 1995 Grand Cherokee. The 42RE was paired with the 4.0L inline-six engine. The 46RH (also known as the A518) was paired with the 5.2L V8 engine. A manual transmission was also available, but it’s much rarer.
42RE Transmission For The 4.0L Engine
The 42RE is a four-speed automatic overdrive transmission. It was built by Chrysler and is known for being fairly reliable when maintained. It uses a lock-up torque converter to improve fuel economy on the highway. This transmission is electronically controlled, which was a step up from older hydraulic-only units.
Common issues with the 42RE include:
- Slipping between gears, especially 2nd and 3rd
- Harsh shifts or delayed engagement
- Torque converter shudder at highway speeds
- Overheating, especially if you tow heavy loads
If you own a 4.0L 1995 Grand Cherokee, the 42RE is what you have. It’s a solid unit, but it needs regular fluid changes to survive past 150,000 miles. Many owners report that the transmission fails around 120,000 to 180,000 miles if neglected.
46RH Transmission For The 5.2L V8
The 46RH is a heavy-duty four-speed automatic. It’s essentially a stronger version of the 42RE, built to handle the extra torque from the 5.2L V8. This transmission is also known as the A518. It features a lock-up torque converter and is partially hydraulic, partially electronic.
The 46RH is generally more durable than the 42RE. However, it’s not immune to problems. Common issues include:
- Loss of overdrive
- Harsh reverse engagement
- Fluid leaks from the front pump seal
- Burned fluid from overheating
The 46RH is a favorite among off-roaders because it can handle bigger tires and more power. If you have the 5.2L V8, you’ve got the stronger transmission. But it still needs care. Neglecting fluid changes will kill it just as fast as the smaller unit.
Manual Transmission Option (AX-15 Or NV3550)
A manual transmission was offered in the 1995 Grand Cherokee, but it’s uncommon. Most were the AX-15 five-speed, which is a tough unit made by Aisin. Later models got the NV3550, but the 1995 typically had the AX-15. This transmission is known for being bulletproof. It’s the same one used in the Jeep Wrangler and Cherokee XJ.
If you have a manual, you’re lucky. The AX-15 can handle a lot of abuse. Common issues are mostly clutch-related, not transmission-related. The main problem is a weak external slave cylinder that can leak. But the gearbox itself rarely fails.
Common Problems With The 1995 Jeep Grand Cherokee Transmission
No matter which transmission you have, there are some shared problems. The 1995 Grand Cherokee is getting old, and age takes a toll on seals and gaskets. Here are the most frequent issues owners report.
Transmission Slipping
Slipping happens when the transmission can’t hold gear. It feels like the engine revs but the vehicle doesn’t accelerate. This is often caused by low fluid, worn clutch packs, or a failing torque converter. Check your fluid level first. If it’s low, top it off and see if the problem goes away. If not, internal damage is likely.
Delayed Or Harsh Shifting
If your transmission hesitates before shifting or slams into gear, it’s a sign of trouble. This can be caused by a faulty shift solenoid, a clogged filter, or low fluid pressure. On the 42RE, this is often the first sign of a failing transmission. On the 46RH, it might be a simple adjustment issue.
Overheating
Transmission overheating is a killer. The 1995 Grand Cherokee’s transmission cooler is built into the radiator. If the radiator fails or gets clogged, the transmission can overheat. This leads to burned fluid and eventual failure. Install an external transmission cooler to prevent this. It’s a cheap upgrade that saves your transmission.
Fluid Leaks
Leaks are common on older vehicles. The most common leak points are the front pump seal, the pan gasket, and the rear seal. A small leak can quickly become a big problem if you don’t address it. Check your fluid level regularly. If you see red fluid under your Jeep, find the source and fix it.
How To Maintain Your 1995 Jeep Grand Cherokee Transmission
Maintenance is the key to a long transmission life. These old transmissions are not as forgiving as modern units. Here’s a step-by-step guide to keeping yours running.
- Check fluid level monthly. With the engine running and transmission in park, pull the dipstick. Fluid should be bright red and smell like oil, not burnt toast.
- Change fluid and filter every 30,000 miles. Drop the pan, replace the filter, and refill with the correct fluid. For the 42RE, use ATF+3 or ATF+4. For the 46RH, use ATF+3 or Dexron III.
- Install an external transmission cooler. This is the best upgrade you can do. It keeps fluid temperatures down, which prevents overheating and extends transmission life.
- Adjust the throttle valve (TV) cable. On the 42RE and 46RH, the TV cable controls shift pressure. If it’s out of adjustment, shifts will be harsh or soft. Adjust it according to the factory service manual.
- Don’t tow in overdrive. If you tow a trailer, lock out overdrive. Overdrive generates more heat, which is bad for the transmission when under load.
Following these steps will double the life of your transmission. Most failures happen because owners ignore the fluid. Don’t be that person.
Upgrading Your 1995 Jeep Grand Cherokee Transmission
If you want more power or plan to off-road, upgrading the transmission is a good idea. There are several options available.
Rebuild With Heavy-Duty Parts
A rebuild is the most common upgrade. You can replace the stock clutch packs with heavy-duty ones. Add a shift kit for firmer shifts. Upgrade the torque converter to a higher stall speed. This makes the transmission stronger and more responsive. A good rebuild can cost between $1,500 and $3,000.
Swap To A Stronger Transmission
Some owners swap in a stronger transmission. For the 4.0L, you can swap in a 46RH from a V8 Grand Cherokee. This requires some modifications, but it’s a direct bolt-on. For the 5.2L, you can swap in a 47RE or 48RE from later Dodge trucks. These are stronger and can handle more power.
Install A Manual Transmission
If you have an automatic and want a manual, you can swap in an AX-15 or NV3550. This is a big project, but it’s rewarding. You’ll need the transmission, clutch pedal assembly, flywheel, and driveshaft. It’s not for beginners, but it’s a popular swap among enthusiasts.
Cost To Replace A 1995 Jeep Grand Cherokee Transmission
If your transmission fails, you have a few options. A used transmission from a salvage yard costs $300 to $800. A rebuilt transmission costs $1,200 to $2,500. A new transmission from Jeep is no longer available, so you’ll have to go aftermarket.
Labor costs vary. A shop will charge $500 to $1,000 to swap a transmission. If you do it yourself, you save that money. But it’s a heavy job. You’ll need a transmission jack and some mechanical experience.
Here’s a quick cost breakdown:
- Used transmission: $300–$800
- Rebuilt transmission: $1,200–$2,500
- Labor: $500–$1,000
- Total for a shop install: $1,700–$3,500
It’s not cheap, but it’s cheaper than buying a new car. And the 1995 Grand Cherokee is worth keeping if the body is rust-free.
Frequently Asked Questions About The 1995 Jeep Grand Cherokee Transmission
What transmission fluid does a 1995 Jeep Grand Cherokee use?
For the 42RE, use ATF+3 or ATF+4. For the 46RH, use ATF+3 or Dexron III. Check your owner’s manual to be sure. Using the wrong fluid can cause shifting problems.
How do I know if my 1995 Grand Cherokee has a 42RE or 46RH?
Look at the transmission pan. The 42RE has a square pan with a rounded corner. The 46RH has a longer, rectangular pan. You can also check the engine. If you have the 4.0L, it’s a 42RE. If you have the 5.2L, it’s a 46RH.
Can I swap a 46RH into my 4.0L 1995 Grand Cherokee?
Yes, but it’s not a direct swap. You’ll need the transmission, torque converter, and possibly a different flexplate. The 46RH is longer, so you may need to modify the crossmember. It’s a common upgrade for more durability.
Why is my 1995 Grand Cherokee transmission slipping?
Low fluid is the most common cause. Check the fluid level first. If it’s full, the problem is internal. Worn clutch packs, a failing torque converter, or a clogged filter can cause slipping. A professional diagnosis is recommended.
How long does a 1995 Jeep Grand Cherokee transmission last?
With regular maintenance, the 42RE and 46RH can last 150,000 to 200,000 miles. Without maintenance, they often fail around 100,000 miles. The manual AX-15 can last 300,000 miles or more with proper care.
Final Thoughts On The 1995 Jeep Grand Cherokee Transmission
Your 1995 Jeep Grand Cherokee transmission is a robust unit if you take care of it. The 42RE and 46RH are both capable, but they need regular fluid changes and coolers to survive. The manual AX-15 is a gem if you can find one. Don’t ignore warning signs like slipping or harsh shifts. Address them early to avoid a full rebuild.
If you’re planning to keep your Grand Cherokee for years to come, invest in a transmission cooler and stay on top of maintenance. These old Jeeps are worth the effort. They have character and capability that modern SUVs lack. With a little love, your 1995 Grand Cherokee will keep rolling for many more miles.
