Jeep motor and Tranny reliability?
 
I am a jeep noob and have been quite surprised by what I have seen.

Been looking at jeeps from 90 to 97. Seems lots of Jeeps get their motors replaced at about 80-90 K miles and trannys seem to go about the same mileage.

These seem like awfully short lifespans for motors and trannys. And these are major driveline components, not like a shock absorber, or a brake pad. Have I been spoiled by my Honda? What can I expect for driveline lifespans? what does it cost to replace these components, and do how does replaced motors and trannys on Jeeps fare on prices?

Thanks in advance

I thougt they were kinda like hammers - hard to wear out or break!

I know there are always a few that cause problems, no matter what brand, but maybe you ought to hear from some of the millions of owners who have had good luck before you make any decisions about whether you want one or not.

BTW, I have a friend who has a 95 with 150,000 miles on his and he revs it up every chance he gets. He's not afraid of the stupid pedal. His has never been apart nor has it needed any type of major mechanical work that wasn't self induced.

i've got 98 tj with 111,000 miles and it doesn't burn oil and it has no leaks.... ($hit i just jinxed myself by saying that!!) clutch will need to be done in the next 5k miles probably...

I've heard of these motors running over 200k and never being taken down, and the ones that do were abused beyond belief. The Jeeps were built to take most of what you can throw at it, that's why after 66yrs they're still one of the most popular vehicles on the road. They get bad fuel mileage, and don't have a lot of room for cargo but they're a Jeep, and it's more of a way of life rather than mode of transportation. I have nothing bad to say about mine, I love it! :D besides, if you buy a new one, you'll get a warranty so you shouldn't worry about it.

When it goes out, at least you can get on here and ask how to fix it! :D

CHEERS!!

yeah agreed jeep engines are know to go forever, i saw an add for an XJ (same angine as a tj i believe) with 250,000 miles

otoh some people have problmes with the tranny's but i would say that that is only .1% of the peoploe who own jeeps, its just that if it does happen they complain a lot because it is like a $3000 problem, overall though jeeps are built bulletproof!

i have 181k on mine and it doesn't show any signs of slowing down. i've never had the first minutes trouble with it. you must be looking in the wrong places if you don't find some with some miles on them. are you talking 4.0 or 4 banger? i know the 4.0 is a reliable workhorse. my fiance has a 99 grand cherokee that has 154k and it runs like a top. these engines last. i came from a honda and still have one, but it just depends on how it was taken care of. just do it, you won't regret buying one.

The straight 6 from chrysler it's well known to last 4 ever!!! that icludes Jeep's.
I saying that because a lot of people told me that,also my father still having He's 93 Grand Cherokee with 170k miles. and he bought it back in the 95 with very low miles.

I agree. The Jeep I6 is bulletproof. Damed things suck up gas like there was no tomorrow, though. I only got about 9mpg on my 93 zj. Had to get rid of it when gas prices inched up to $3/gallon. My 98 tj's giving me about 15mpg, which is very reasonable--for a Jeep!
