I have a 95 Discovery with 174,000 miles, It loses speed went traveling at highway speeds, but the rpm gage still reads 2500. Is there any one know what causes this problem. When I push down on the gas paddle the rpm goes up and I began to lose speed. Thank in advance to anyone that can help.

 

Is this a manual or automatic tranny.Either way, you may be loosing a clutch or tranny may be having a problem.
