Drivetrain 3rd Gear RPMs hang around 4000

I had 2 kind of problems, that in both the 3rd gear was too late OR sometime wont even and "as my best describe of the thing " is shiffting back wards getting back to the 2nd and the service engine soon start blinking AND the OD green light blink too .

the first thing was that one day was driving under the rain, and did not see that ROCK and the HOLE filled with water just after it, and the ROCK hit the under part of the gear, crack it, and while I jumped in that hole filled with water, some water came inside to the " what the mechanic name it for me " the brain OR the computer of the Gear, where I had to replace that part and fix that crack,.


the other time . I had a very bad shifting problem , and the same mechanic said that my clutch was a little consumed , and need to be replaced, but he offered another thing which he pushed the clutch , and said this must work for you for few weeks, that was 6 months ago, and thank god, still in a good shape

hope these info was useful bro, keep us updated
