So I have done a ton a research on this topic and I'm still having issues. My tranny wants to launch in either 3 or 4th. Either way its not 1st. So I replaced the solenoids, fluid and filter. Did not change anything. I replaced the TPS. Still not working. I replaced the TCM. Nothing. I double checked the ground strap on the back of the head. I traced as much of the tranny wires as I could to check for shorts and burned off wires. I also checked fuses. I read that the NSS can relay info to the TCM so I replaced that for the heck of it and here is the kicker. Its a brand new transmission. The guy I bought it from left the records in the console, but I have no leg to stand on as far as warranty because I'm not the guy who had the work done. What am I missing? How often do solenoid wires short out?

My 96 XJ did the same thing last year. Would start out in third gear. Was a small 10 amp fuse in the power distribution box under the hood. Was'nt blown, just not making good contact. Pulled it out and cleaned it, tranny has been perfect since.

I forget what year they stopped using this fuse....Had it in 90 for sure.

Well I checked for the fuse and did not find one. Mine is under the hood and I did what watertrucker did. It looked fine but I replaced it anyways. Are there any relays?

Ok so I'll drive it again tomorrow and check the new fuse, but I did some more reading tonight and I think I may have it nailed. I might try to replace that tomorrow and see what happens. Thinking its either the ISS or OSS or both. Only thing I have not tried replacing/testing yet.

Did did you have any luck having almost the same issue I have to drive an automatic through each gear until I reach drive then it drives perfectly normal and I have done pretty much everything you are saying you've done I've replace the solenoids fluid filters checked fuses not sure where exactly the fuses I need to be checking are located for a 95 but did you have any luck and what is a i s s exactly

This post is from 2015 so not sure if you'll get a response or not 95 should have a fuse somewhere in the harness going to/from the TCU.

do you have reverse lights?
