I changed my transmission fluid today, then flushed the radiator. Disconnected the battery for a few minutes while working on the radiator. Everything went well, and the truck runs fine, but my speedometer stopped working. Any ideas to as why? Maybe a blown fuse? Don't think I got the speed sensor wet or anything.

 

What year is your truck? Engine? Trans? 2 or 4 wheel drive?

 

98, 5.9l. 46re auto, 4x4

 

Ok, on yours, the Speedo gets its cue from the rear wheel speed sensor on the top of the rear diff. Check and make sure it didn't simply get unplugged, bumped, broken, or otherwise disturbed during the trans swap process.

 

Thanks. I'll check it
