Anyone ever seen this I was cruising at 70 I have 35s and a gps but this is what my dash said? Peggin 6k ain't know way but it set there for 10miles I tried letting off and it would Drop to 5 but when I touched the gas it would peg 6 again. Came to a red light. When I pulled off from the red light got back up to 70 was Sittin on 3k.

There was no way I was turning that high sounded normal. Prolly around 2-2.5k

1993 bronco

35" mud tires
3.55 open rear. ( I know need to work on that)

 

Sounds like the transmission slipping...might try changing the fluid and filter and adding some Lucas oil stabilizer and see if it helps.

 

could be a short in the tach wiring

 

You think the tranny slipping could do that? Didn't sound any different, like it was runnin a higher rpm.. I need to change the tranny fluid and filter anyways.

 

If it didn't sound any different then it's probably a tach issue.
