Last Updated on October 23, 2023 by Robert Wilson

The 46RH transmission was introduced in the early 1990s as an upgrade to the 44RH.

It was designed for use in light duty trucks and vans equipped with V8 engines.

The 46RH is a four speed automatic transmission that uses hydraulics to control the shifting of gears.

The transmission is controlled by a computer, which tells the transmission when to shift gears based on input from various sensors.

The 46RH has been used in a variety of vehicles, including the Dodge Ram 1500, 2500 and 3500 trucks, as well as the Jeep Grand Cherokee.

Some of the common 46RH transmission issues are – Gear Slippage, Fluid Leaks, Delayed Shifting, Overheating, Noises, Fluid Contamination, Electrical Problems, Torque Converter issue, Valve Body Malfunctions and TCM Failures.

These problems can be traced back to a number of factors, including poor quality control during manufacturing, incorrect installation of the transmission, and faulty parts.

What is a 46Rh Transmission?

The 46RH transmission is a 4 speed automatic transmission that was used in Chrysler vehicles from 1989-1993.

It is very similar to the 42LE transmission, but has a few key differences. The 46RH is a heavier duty transmission and can handle more power than the 42LE.

It also has a higher first gear ratio, which gives it better performance off the line.

However, the 46RH is not as fuel efficient as the 42LE and has a tendency to overheat if pushed hard.

What Year Ram Has Transmission Problems?

There have been a number of reports of transmission problems with the RAM 1500, especially in model years 2009 and 2010.

Some owners have reported that their trucks needed to be completely rebuilt or replaced after only a few years and tens of thousands of miles.

If you own a RAM 1500 and are having transmission problems, you may be able to get help from Chrysler.

In 2015, Chrysler issued a “Customer Satisfaction Notification” for certain model year 2009-2012 RAM 1500 trucks that were equipped with the 5-45RFE automatic transmission.

This notification offered extended coverage for repairs related to the transmission on these vehicles.

So if your truck is covered by this notification, you may be able to get repairs done at no cost to you.

If your truck is still under its original factory warranty, you should also contact Chrysler customer service to see if they will cover the costs of repairs or replacement.

There have been some issues reported with them, but overall they seem to be pretty solid and reliable.
