Where is the transmission? How hard would it be to change the output speed sensor for a 1999 Jeep Grand Cherokee Laredo? Should I attempt it myself or should I spend the extra $60-$80 to get it repaired? Thanks.

Hey James,
Ummmmm. Gotta be honest James and I love ya like a brother :shock: LOL but if ya gotta ask where the transmission is then. It may be in your best interest and save ya a ton of aggravation, to have someone else do it. Seriously James, I would recommend you have a trusted shop take care of that for ya!

I figured that, but I want to learn. I've been interested in learning about cars, but I never have any time. I went through school, joined the military, and all I have time to do is train. There has to be someone on here that can teach me at least a little something. I read that the speed sensors aren't hard to get off at all, but I don't know where to begin. Is there a place online that'll teach some basics?

James,
There is a ton of info like that here on this site, surf around a bit. Also being a technician trainer, I would also recommend you start w/ some basics first before you try to tackle the more advanced jobs. Yes speed sensors can be easy to change, but they can also be a big pain at times! Not to mention the fact that on some trannys, there can be up to 4 of those sensors in different positions! And identifying the right sensor would be critical! (They all pretty much look the same)
I would recommend you purchase a manual about your vehicle and read up on it. Then do some of the basics, ie: oil change and lube, maybe a tire rotation, small maint. Items of that nature to kind of break yourself in! Also stay active in this forum! There is a ton of great info here and the guys here really know their stuff! So ask more questions! Any one of us are happy to help! Hope this sheds some light for ya and take care!

Chris

p.S. Thanks for your sense of humor! I wasn't trying to belittle you or any of that nonsense! Its good to see folks interested in there own vehicle maint! Feel free to email me any time w/ your questions!

Well being a Marine makes it easy for me to have thick skin. I do appreciate your advise, I'm taking it to AAMCO today to get it checked out. The output speed sensor was said to be the problem with this other place, but once I filled up with gas, it worked fine again. Are there any other reasons for it not shifting into a higher gear?

James! Retired Navy here! (Chief Machinist Mate, bilge rat!) LOL Yes the reason it won't shift is that when the sensor "codes out" the tranny will go into "limp in" mode to minimize the risk of damage and tell you there is a problem. Once the repairs are complete you should be all set!

If you want to start making these repairs yourself I would definately spend the 20 or so bucks and buy a Haynes service manual. They are vehicle specific and very easy to follow for anyone. I won't own a vehilce without having one on the shelf. They are available at most good part houses and will save you more time and aggrevation than any tool in your your box. Chiltons are also available but I really prefer the Haynes. This repair should not be difficult at all but know what your getting into in detail before you start. A manual is the ticket to repair bliss. Good luck.
