What would cause a 1988 Jeep Cherokee to drop out of overdrive?

Answer 1

Check your NSS Neutral Safety Switch. It has connections inside to let the trans go into the gears, including controling the reverse lights. It is located on the passenger side of your Jeep on the side of the trans. Here is a website that will help with it. http://jeepin.com/features/nss/ You could also have a bad Tourque Converter. You might have a bad Solonoid at the trans that would control the turning on and off of the OverDrive. You might want to get an opinion at a trans shop before doing any else first. I hope this helps you.

Answer 2

You have to put your hand on the gear lever and move it into second gear at the same time depress the clutch pedal under your left foor, then lift your left foot of the clutch and depress your right foor on the gas pedal. That should do the trick! If it is an automatic transmission, ask your local mechanic

Answer 3

I have to assume this is something going wrong.

The trans will down shift for the following reasons:

• Throttle application has increased to the point it down shifts, if the engine runs poorly or is not making the correct power this can happen.
• Low oil in trans
• Transmission overheating.
• Computer control fault, either a solenoid inside the transmission, a wring problem or similar issue.
• The inside of the transmission has an issue.

Good Luck
