I just converted my 2wd 1990 Jeep Cherokee 4.0L to 4wd. This included changing the transmission. It is still a AW4, I just swapped it for one out of a 4wd XJ. Since I changed transmissions I have noticed a significant loss of performance. It seems to have a slow mushy shift. It's not very noticable during normal driving, but very noticable when I get into the gas. I seems to take longer to shift than it did before and reaches 500+ higher RPMs before completing the shift than it used too.
My friend who has been helping me with the conversion said it feels fine to him, but then he doesn't drive it every day and has never owned an XJ, so he doesn't know how it performed before or what is normally feels like.
Is it normal to lose some performance in 2wd after converting to 4wd? Does the transfercase cause the transmission to perform differently in 2wd?
The trans we put in the vehicle is used and was said to be working when pulled from the other XJ, that's all I really know about it.
