Not impressed with 2010 Jeep

[SLCraig]

You think the 3.8 is bad, you should see the 3.7... An engine that should never have existed. Reliable, but just lackluster performance in every respect.

nah, wont have that issue, have a Durango to tow with, with the tow package,3.92 gears and 4wd with 4-lo. Has heavy duty cooling and large brakes

Don't own a boat but have pulled full dress 69 RR and trailer quite easily, have class 4 hitch and brake controller. Durango is rated to tow 7350 lbs with 3.92 gears.

I am not a tool like Mr Crv who put public safety at risk by grossly exceeding the limits of his Cute utility vehichle because of his stupidity. There is a reason OEM's publish safe towing limits and why law enforcement up my way pull people over and pop em on scales!
I work for a utility and most of have to have CDL's. We have MMTA come in and teach classes, they show us some nice slides of people who ignore their tow ratings and the carnage.

Possibly it was undergeared. Mine has 4.10s, the one mentioned could have 3.21s.


I think a few actually got 3.07's.

The old 4.0L I6 was a great engine. It didn't look as good on paper as the 3.8 but they felt (and performed) much better.

The problem with the 4.0 was they came with 3.07 gearing with 5 speed manual (unless Rubicon).


You have it backwards...most 4.0/5-speed Wranglers had 3.54 gears. (2.5's usually got 4.11's.) The automatics (no OD until, IIRC, 2001) had 3.07's. 5-speed XJ Cherokees had 3.07's, autos having 3.54's.

wouldn't take off on a moderate hill in 1st gear in 2 Hi


The OP made it sound like, after it was out of the water, he couldn't get it started on dry ground, on a moderate hill, w/o resorting to 4LO.


It sounds to me like his biggest problem was in the driver's seat!

Another 3.8 liter V6 I am familiar with, the Buick 231/3800, exhibited none of the puniness of the 3.8 Chrysler Jeep motor. I've had two of them, a carbed 1975, and an injected 1996 in a full size Olds 98 Regency. Adequate power and good economy. The Regency got 26 MPG on a good day. Pulled small trailers just fine too.

Much better torque curve than the 3.8 Chrysler, more low end, and more enjoyable to drive. I think the 231 Buick was offered in jeeps back in the 1960s or 1970s, or it was a common engine swap. Motor was designed in the early 1960s. Too bad Chrysler didn't just use that instead of making their own lesser motor.

GM sold the tooling and rights to the Buick V6 to Jeep in the 60's. GM was selling lots of big V8s, and thought the V6 was history for them. The Buick V6 installed in Jeeps was called Dauntless 225.

AMC bought Jeep and had their own inline 6, and with the fuel crunch in the early 1970's, GM bought back the rights to the Buick V6 which they installed in 1975 cars. GM bought rights in April and was producing engines by fall, hastened by the machine foundations for the tooling still being in place.

We had a 97 and 01 with 3.07 gears and 5 speed transmission. There was an option to pay to get the "heavy duty" suspension package on TJ Sports that came with rear 44 and 3.73 gears.

2.5s with 3 speed auto had 3.73s, and with the 5 speed manual had 4.10s.

No idea what the neon engine / OD automatic came with. Those are still too expensive for me to look at.
