    Why is my car downshifting more and not maintaining speed when climbing hills?
    216, 000 miles, bought the car from a friend about 5 months ago, no real issues. I just noticed this problem yesterday when going up a mountain pass near my hometown. I used to easily be able to maintain 55-65, but now I cannot go 40 even with the gas pedal all the ...

      You'd better use a professional Hyundai diagnostic tool, so relatively safe, I think GDS VCI Diagnostic Tool on the good, GDS VCI Diagnostic Tool( http://www.aobd2shop.com/.../...gnostic-tool.html) is an advanced service system that provides comprehensive coverage for all Hyundai vehicles including all Hybrid cars. GDS provides complete diagnostics, analysis and reprogramming capabilities as well as a huge library of technical, service and repair information.of course, if you believe that you can solve the problem yourself, or consult a professional mechanic,hope it is helpful to you.

      I would have the catalytic converter checked out. Have vacuum gauge connected to test the vacuum at idle and when the car is revved. Old cats can cause issues with maintaining vehicle speed. If the cat core has melted down a bit, it will cause restriction. Remember, in an engine; what goes in must come out. If not enough air can escape from the exhaust, not enough will be allowed into the engine.

      Replace the clutch throwout bearing. In fact, with the high labor cost involved - it's just as well to go ahead and replace the clutch kit as an assembly.

      The clutch kit; friction disk, bearing, pressure plate - are all usually replaced at the same time - since the transmission needs to be removed anyway, and these other related parts will have the same basic age and wear.

      Check these various on-line vendors; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, to list only a few. For example, they (RockAuto) list the clutch kit from around $115.00 for your vehicle.

    Is it a Transmission issue or something else?
    I start the car and the transmission doesn't fully engage ( It revs, doesn't accelerate well and won't change gears). Additionally, the Air Conditioning won't immediately turn on. I drive for maybe 5-10 minutes and both the transmission and the Aircon fully engage. ...

      it would be the transmission but could be something not real serious check the transmission fluid if it is low fill it the oil should be red if it is black or brown something has slipped enough to burn the oil you can try to change it and the filter but it's a fifty fifty on if its too late.

      The internal seals inside your transmission need replacing. I have seen this happen before. On a scale of 1-10 this is a 8-9 skill job, requires removing and disassembling transmission. Good luck

    When I am at a stop and in drive the car makes lunging or jumping movements.
    I only have this problem when the weather outside is hot ( about 88 degrees and above ). Early mornings and at night I have no problems what so ever. There are no warning lights on and the motor has 145,000 miles.

    Car suddenly slows down then wont switch gears
    My Hyundai will suddenly slow down on the highway. No matter how much you push on the gas it will not switch out of second gear. You stop the car, turn it off and then is fine. Sometimes there is no problem at all. No check lights are on.

    Why wont my car move? My automatic car wont even budge to go into gear and can't move.
    ll of a sudden the car shift went out. Is it the linkage? Transmission? Fuse? It started out that the care wouldn't go into park. Then not even a week later I can't even move the shifter. It is registering in neutral, but I can't even roll the car at all. It's like ...

    Dealer says I need my crank position sensor replaced. Is that the same as the crankshaft position sensor?
    They also are telling me it takes 2 hours to replace. The AutoMD says 24 minutes. Am I getting screwed here??

      There is a difference between the crank sensor and a cam sensor . In both cases they tell the ecm what the motor is doing for timing and other things . If your not sure if they are being fair or over charging take it to someone else . If your doctor told you they needed to do a heart trans plant on you would you go ask someone else . Mech's are car doctors . Some good some bad .

      For the start up issue when was your last tune up( plugs, wires, filters)? could also be the gas your using. The shaking around 60 could be one or both CV axles are going out.
