3000rpm's at 75 mph

[timelessconstructionllc]

My truck is running 3000 rpm at 75 miles an hour. My truck is in my sig. Before this truck I had an 05 with the same set up except I had a Dr performance module instead of edge and I could go 90 mph without red lining it. Any knowledge or advice would be greatly appreciated

Sounds like the converter may not be locking up . What gears do you have ?

Look on the info tag,, should be on the glove box door inside .

Keep an eye on your tach. If it bounces around at idle, it's going bad. My tach shows well over 3200 almost every time it shifts down. There is another thread going on about bad tachs in 06's.

Does your engine sound like it's running that fast?

There isn't a tag inside the glovebox. My vin is 3d7mx48c96g260264 if anyone can run it. Is there anywhere else that the gears would be listed.

Either its not going into OD, or, the tach is messed up.



If there is no tag in the glove box it has 3. 73 gears.



You should be able to tell just listening to the engine if its actually turning 3000 rpms. They make a LOT of noise at those rpms.

I'm not sure which it is but I am hoping and leaning towards the tach BC When I hit the button yo turn the OD off the engine runs noticeably faster. I'm gonna check out the tach thread

You need a new instrument cluster, common problem.
