My car when reaching 60mph in the highest gear possible just doesnt go further than that. Starts to rumble loudly like if it was in a lower gear and doesnt gather speed. Its a 99 Ford Focus?

Answer 1

The way you describe It sounds like it is stuck in gear. The average max speed for a 99 Ford focus stock is around 115 mph. And the rumbling sound is most likely the rev limiter topping off. I would have your transmission and fluid checked. But it definitely sounds like a clutch plate sticking. Yes this can happen in automatic transmissions. It could be something as simple as adding Transmission Fluid or as complicated as getting a new transmission or transmission filter. To check trans fluid get some wheel chocks and put them near the front tires both in front and behind, make sure ground is level, after key in ignition turn key just before start press brake and shift through the gears one at a time P,N,R,D,L is standard then shift back to park and turn key to start engine let sit in idle for a little bit then take it around a block after removing the wheel chocks must be running. Then check transmission fluid. Be-careful to not wear loose clothing as it could get caught in the radiator fan. I recommend to follow your owners manual for specified transmission fluid.
