Good idea, hopefully the source of the leak, and new filter & fluid will put you back on the road in running order. The slippage was caused by the leak, causing low fluid level. Keep fingers crossed that you shut it down soon enough that it didn't cause extensive damage internally in transmission. Don't forget, when you get diagnosis & repair estimate, if it sounds too high, you have the option of a second opinion, so feel free to get back to us, or consult with another repair shop, or transmission repair place for advice on estimate, before you commit. Good Luck, and keep us posted.

I would consider changing the vehicle speed sensor. When they go bad, they can really throw out a lot of bad data to the computer, resulting in unexpected behavior like you're experiencing. They're only around $20-$25. I hope this helps! :)

Hi Tom your vehicle is equipped with a Rev limiter it will not allow you to rev the engine above 4000 with the trans in park; as for the first problem you may have one of two things, one of the spark plugs or spark plug wires is bad or you have a flat spot on the throttle positioning sensor in which case have be replaced. Good luck?

Just purchased my 2nd used Hyundai accent gs- 57,000 miles. I have been researching the cars problem of: 75 mph; in 5th gear, the rpm's are over 4000; making the engine noise almost unbearable! So what...


any "adjustments" you carry out to reduce engine speed at any given road speed will affect the speedo/odometer reading,BUT,the simplest/cheapest way of reducing revs is to fit bigger wheels/ tyres.say fit 15" instead of 13"with the same profile tyres.this will reduce your revs by about 500 @75mph.but the speedo will read 70mph.also acceleration times will be considerably reduced.and put an extra strain on the clutch/engine.
alternatively,swop the whole drivetrain to diesel,75mph=3500.

Is there anything I could do to bring my RPM's down when Im driving in hwy. I have a 96 t100 4x4 stick, stock. At 70mph rpm is at 3300. I changed to manual hubs and that helps a little.


The only way to accomplish that is to change the axle gear ratio. Trucks are generally geared for hauling, towing, plowing, etc, so you have more torque and power at lower speeds. If you change the axle ratio,your low end performance will probably suffer (sluggish acceleration at low speed). Basically, your T100 is not designed for 70mph highway driving.

Do you get a check-engine light, or does the transmission O/D light flash? Many times, this is due to a speed sensor on the transmission. When the sensor goes, the transmission has to do default shift timing and it will shift very late. Usually, this will set a code in the onboard computer.

Since RPM meter is also important so that you can control the engine from overspeed. It is also important to repair the thing your rpm cable maybe worn out already. If it is an electronic rpm meter cold Solder in electronic lead might be the cause.
