I have a 1991 Dodge B150 RamVan with 5.2L and OD cut-off switch on dash.

What size and stall speed torque converter should I get?

I put my info in a stores website and it shows different depths and stall speeds. How do I decide?

 

Stick with stock stall speed. (I think around 1600-1800) Unless you have some performance upgrades, stock is all you need. Buy a GOOD one though, an 80 dollar t/c is NOT a 'good' one.

Why are you replacing the t/c in the first place?

 

I don't know stock spec.

When I enter make/model into Autozone the "vehicle specific" results returned options with 24 to 31 splines and starting stall speeds ranging from 2400 to 3200.

I can count the splines, but not depth and stall speed.

 

Which transmission do you have?

 

The A904/A500. Here is a pic of the ID tag

 

i am told it is the A904 transmission, but when you add the overdrive, the assembly is then an "A500"
