2005 2005hyundai elantra replaced input and output speed sensors now I don't have high gear not shifting right

 

Hi Denny,
Can you bring us up to date?
What was the original problem?
Jumping to conclusions and replacing parts, especially good parts, can get expensive and disappointing.
From my experience, the problems from malfunctioning sensors is about equal to "poor electrical connections" which increases with age.

 

I replaced input and output speed sensors because. The transmission started revving up instead of shifting properly .

 

It was not shifting properly revving up between gears and tacind high

 

It was revving high between gears not shifting right I checked all plugs except internal transmission. Changed fluid used correct type so then I replaced speed sensors

I'm not too sure speed sensors are the problem.
Sometimes valves in the trans valve body cause these problems, and so can poor line pressure to apply clutches. If it is happening with different speeds and gears , it may be a pressure regulation problem. It is rare for all clutches to go bad all at once , except if the fluid became contaminated.

 

Would have tried a drain and fill to see that would improve things
