Hi, I have an 88 Ram 4x4, and I am getting killed on the fuel economy with a 3 speed auto... but I cant afford to do a full tranny job right now and upgrade to a 4 speed.... I was wondering if it is possible to change the High Range gear in the t-case to get better road speed gearing. Is this an option for me??? Thanks a lot

 

I do not believe it is possible to change gear ratios in our t-cases.
