jeep grand cherokee laredo cant go more than 30 mph

[Stephen]

we have a 2007 jeep grand cherokee laredo and tonight my mom was driving and couldnt go more than 30 mph. she called my uncle who is a mechanic and said to check the transmission fluid?
the other thought was it might be in limp mode?

Did she slip it into low gear?


Funny story:

My uncle borrowed my dad's pickup when I was young. He called him frantic that the transmission had gone out. He had it towed to a shop, and he had the transfer case in neutral.

If the Cat Converter is totally clogged up It wont go very fast... happened to my dodge ram truck.Thought for sure it was the trans, but the cat was melted and couldn't get any air past making it go like 20 mph.

So it was in low range and she was too embarrassed to admit it?

yea, about that...

i dont think so, because my dad drove it too and had the same problem. my guess is there might be some condensation in the gas from the humidity and due to the fact that her gas gauge is never above 1/4 of a tank (which pisses me off to no end)

That might help, and doing some Googling, there seems to be issues with the input/output shaft speed sensors on the trans with these.

Good luck.

Looks like they go for about 30 bucks a piece. There are two. I am not 100% positive this is what it is, but it has possibilities.
