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.
no. 1986 to 1990 sorry
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.
It was an option
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.
Driver side of firewall.
for most parts, yes
