Hello scotty I have a 4 wheel drive 1990 Ford Bronco II with a 2.9L v6 and a A4LD automatic transmission. It is lifted with 32 inch tires. I bought it off of craigslist a year and a half ago. I recently noticed that my RPMS while I'm driving are around 4k at 65 MPH. I tried looking on the internet but I couldn't find out anything accept that my RPMS should be around 2K RPMS depending on gearing. The truck seems to go into all gears including overdrive when I move the column shifter into each gear. Any advice is appreciated. Thanks for your time. Michael McVae.

Thank you for the replys. It didn't seem like anything was to wrong since it drove fine and it didn't seem to lack any power for its age and what it has under the hood. I just figured I would ask to check. I know how to check rear end gear ratio but how would I go about checking the transmission gear ratio?

Mods can mod other systems you don't want modded. Another endorsement for restoring to Stock Specifications.

Realize tire size has a lot to do with rpms at speed. Plus they may have changed gear ratios in tranny or rear end too
