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.
possable a fuse is blown
A 1988 Jeep Cherokee has one oxygen sensor.
An AW4 transmission from a 1991 Jeep Cherokee will not fit into a 1988 Jeep Cherokee. The transmissions in the varying years do not appear to be compatible with one another.

Mona Lisa Overdrive was created in 1988.
A 1988 Jeep Cherokee has one oxygen sensor.
If a 1988 Mercury Grand Marquis shifting out of second gear gets choppy after acceleration then the overdrive band may need servicing. An overdrive band that is sticking can also cause this problem.

Yes you can
The transmission oil line from a 1991 model of a Jeep Cherokee will fit a 1988 model of a Jeep Cherokee because the transmission oil line fits all Cherokee models that were made between 1987 and 1996.
I would assume it would. I haven't worked with those specific years but everything I've seen with the Cherokee(and jeep in general) is that most years are interchangeable as long as they are same engine size.
