I am considering purchase of a 1999 Ram van with less than 50,000 miles. The engine is a 3.9l V6 and the transmission is a 32RH. What sort of gas mileage should I expect on the highway if I drive at or below the speed limit? Thanks.

 

12-15 mpg.

 

Thanks. Is there a drop in replacement transmission that would improve that mileage? a 4-speed perhaps?

 

Doesn't it have 3 speeds and an overdrive?

 

I have not driven the van and know nothing beyond what I have read, which is that the 32RH is a 3 speed automatic with no overdrive.

 

Should already be 4 speed. It's a full size truck with a V6. Not much you can do.

 

So a 32RH has an overdrive?

 

General break down of the numbers Chrysler used in our generation of vehicles;

3- number of gears
2- torque rating (no clue if this actually figures to a number, but is a rating system from 0-8= weak to strong)
R- rear wheel drive
H- hydraulic shift

Forward gears- 3 or 4
Torque rating- 0-8 (1-9 on Wikipedia)
Drive type- R= rear wheel, T= transverse, A= all wheel
Shift Control- H= hydraulic, E= electronic

These could be wrong, but they are the most common I could find with a quick Google search.

 

EPA is actually a good guide (who would have thought that?). By the looks of the ratings, move up to a 318 4speed for better highway mileage.
