Question about 2000 Mercury Cougar

3 Answers

Shifting problems on my 2000 mercury cougar i drive for about 10 mins and when it gets hot it will come out of overdrive. the longer i drive the worse it gets. sometimes it will go into neutral then 2nd and really jerks the car hard. cant drive it long distances. the car never gets over normal operating temperature. at night, when the lights are on, when it starts doing it the lights dim very erratically. no one seems to know what the problem is.

Hello, has anyone changed the transmission filter? if not, this is likely your base problem, a restricted filter will cause low line pressure too and from tourque convertor and cause engine too drag and shift very harshly.........good luck, marty

I have a 2001 Mercury Cougar. It throws code p1780. I have replaced the Neutral Safety switch and still throwing the same code.

The overdrive button is different than a neutral start switch. Your problem could be underneath the car where the transmission wires plug in.

I have a 2000 mercury cougar that is not getting any spark. I changed the coil, crank and cam sensors. The hot wire to the coil is hot when the key is turned, but no spark is getting to the plugs.

You need to run the OBD2 Diagnostics. You will need to have someone hook up a scanner to the vehicle and retrieve the codes. This is the best place to start.

The overdrive is not working

Cars that old usually encounter faulty over drive problems. It burnt out so many miles ago. It's probably a good thing...over drive's that old usually run your engine hot anyways.
