Why is my 2000 kia sportage 4x4 getting such a high tach reading2700 or higherwhen i drive 50 mph or faster with it in 5th gear?

Kia Forum

Sounds like ther is a selector problem in the gear box. Take off the top, where the gear lever goes in and have a look. if there is anything wrong there the box will have to come out.

the transmittion keeps shifting in & out of gear between 45 & 50 mph it shifts to a higher gear then a lower then higher then lower till I get above 50 mph whats the problem & how to fix it

It has to be 4x4

Hello. Welcome to FixYa. I am Toyota Ed, and I will be assisting you today.

The Overdrive function allows the transmission to shift an extra time, sort of like selecting 5th gear in a 5 speed manual transmission. The Overdrive, when used, will save you gas, as the engine is no longer maintaining a high RPM at normal driving speed. Look at the tach whilst driving about 45 mph, and engage/disengage the OD. You will see the tach RPM raise when the OD is off.
More RPM = lower fuel mileage,

The ECT is a different circumstance. The ECT button is used primarily when you have a heavy load in the car, or are towing something. All the ECT button does, when it is engaged, is lengthen the shift points as the transmission upshifts. Normally, the transaxle will shift into 2nd gear at 18-21 mph. When the ECT is engaged, the transaxle will shift in the area of 22 -24 mph. In short, the ECT just makes the time to the 1-2 and the 2-3 upshift longer, to compensate for the additional load being carried/towed.

I hope my assistance answers your question.

your trannny is suffering internal damage... you will have to take it to a shop that services tranny to find out exactly whats going wrong with it... but its not the clucth if your wondering it can be either the syncros going bad or the shift selecter etc....advise taking it into a shop and getting service

if its a automatic and the engine is cold it wont shift into the last gear. the tranny and engine have to be at close to normal running temp to shift. its normal and nothing to freak over. if this isn't the case go to kia-forums.com/1g-1994-2002-sportage/ and post a thread there or look for one. great site

The last shift is not a real gear shift, it is called "torque converter". The high rpms happens because the transm. goes to neutral. Get it to a transm. shop to be tested

popping out of gear means your shifting forks need adjustment, same as the grinding. the tranny is probably good, just the top part, the shifting mechanism needs to be repaired, so it would be cheaper to repair than rebuilding the whole transmision.still, im guessing about 300-500$ depending where you live.
