This will help.

Thanks.

If your transmission is leaking, that would explain the transmission not wanting to shift into other gears. An automatic transmission works off of pressure and when enough pressure builds up the valve body will switch to another gear. The most common places that a front wheel drive transmission will leak is the axle seals, there are two of them, one for each of the front axles. Another problem area is the transmission pan gasket and the transmission lines. None of which are really a hard fix. Do not drive the car if with the transmission fluid level low as you will damage the transmission and will be looking at one heck of a repair bill. Also, make sure that you use dex/merc transmission fluid that is approved for your cars transmission. There are several different brands and types available and although they are all automatic transmission fluids, there is a significant difference in them.

Problem with this is that it could be a number of things, have ur water pump checked, open the radiator and see if there is water running through it, a bad or plugged thermostat, in this case it does sound like a blown head gasket. id suggest flushing the radiator with some cleaner that u can buy at the store and check n see if ur thermostat is stuck, hope for the best and expect the worst

Fluid level ok? Check it when hot and car running.

Have you had the tranny serviced recently?

This type of tranny uses the Dextron +4 fluid, any other fluid would mess up the transmission.

I have a 1999 Intrepid, no problem w tranny, but a month ago I put an aditive that a friend recomended. After only about 5 miles I felt the car more responsive and with more power. I also think my gas mileage improved.

I got it at AutoZone the brand is RISLONE Transmission Stop Slip with Leak Repair
it says works with all types of fluids.

I hope this will help. Good luck

they are behind the cam shaft gears you have to remove then and put the car back in time you might want to go down and get a book to show you timing marks

you might call another shop and ask them about a detenete cable that helps the tranny shift..it wouldnt take a complete rebuild to fix a hard downshift if its something as simple as a detente cable
