#2567 of 4608 Re: Transmission Problem Question... [txman1] by gccambridge Jan 25, 2006 (6:45 pm)
Replying to: txman1 (Jan 25, 2006 1:18 pm) txman1,   Thanks for the response. Interesting. Dealer's answer to me was Euro (Mercedes) trannies are harsher and that new trannies designed with less "slip" to prolong life... I actually took it to another dealer today (second opinion wouldn't hurt). So far, they seem mystified and have actually held the Jeep overnight for "more tests"... Will let you know what the diagnosis is.   I also reviewed the gear ratios and while there is a difference in ratios b/w the 3.7 tranny (Mercedes) and 4.7/Hemi tranny (Chrysler) - relatively speaking, differences don't seem that huge (I've driven a Durango with the Hemi and same Chrysler transmission and it shifted fine across all gears too)... This tranny is used in several Mercedes cars (E Class for example) since 1995 - makes me wonder, could they really all be like that?

Replying to: dakotarae1 (Jan 25, 2006 2:27 pm) Your transmission is the 45RFE, which they began using in the '99 and later models (WJ's). This transmission does not require band adjustments, so don't let any shops tell you otherwise. I also have a 2000 Grand Cherokee Laredo. Since they recognized the problem with yours, did they tell you what it was exactly? I'm having the exact same problem with mine, but I don't have the extra cash lying around to "guess" at what the problem may or may not be. I've got a couple of good ideas of what it is, but I was wondering if you knew EXACTLY what it is. Anyway, I'll check back for a reply, and I hope this information helped you out a bit! If you can tell me what has to be done or replaced, I'll do it and then post my findings and steps used to fix it.
#2574 of 4608 Grand Cherokee 4.7 L Milage? by clarkkent Jan 27, 2006 (7:01 am)
I have a 2000 GC 4.7 L. I just got back from a 4000 mile trip. I have 95000 on the car, good air pressure in the tires, a recent tune up, and I got an average of 17 mpg.   It was mostly HW miles at 75 mph.   Is that about the right mileage?   I would have expected 19 to 20 as it was level cruising with the Cruise Control most of the time.   What is everyone else getting?   Thanks, CK

Replying to: dakotarae1 (Jan 25, 2006 2:27 pm) Hey,I didn't actually leave it with them..had to straighten some things out with my warranty, anyway, they have no clue they said they'd have to tear it down. So, no clue yet! This sucks, I've put so much money into the looks of this thing for it to be doing this.
#2576 of 4608 Re: A lift for my jeep [jeeper96] by dixiecrawler Jan 27, 2006 (7:21 pm)
Replying to: jeeper96 (Jan 25, 2006 7:45 am) Hey, here is some info that may help you out. I believe you said your tires are 235/75-15's, which are a metric size and are probably the stock size for your truck. These are somewhere around 28.9" tall, when they come off the tire line. After they're mounted on rims, aired up, and 4,000+ lbs of Grand Cherokee is dropped on them, they're actually somewhere between 27.5" and 28" tall. For future reference, to convert a metric tire size (235/75-15) to a standard Light Truck tire size (31x10.50R15, for example), use this formula: Width x Aspect Ratio = Section Height; Section Height x 2 = Combined Section Height; Combined Section Height + Wheel Diameter = Tire Diameter; (Example: 235/75-15) 235mm x .75 = 176.25mm (a ratio is a percent; 75%or.75); 176.25mm x 2 = 352.5mm (section above and below rim); [Then you need to convert the mm to inches by dividing by 25.4, which makes 352.5mm = 13.9"] 13.9" + 15" = 28.9" tire height. (I actually had to relearn that formula as I was typing it!) Now that you know your current tire height in inches, we can forget about that for a while. I noticed that someone else replied to you about your tires and whether or not they rub. If they do, something isn't right! That "grind" you hear has got to be either some of your inner fenderwell is lose or something not related to your tires. As far as being easier to flip, the higher your center of gravity, the higher your chance of rolling. Most rollovers can be prevented by the driver. Once lifted, you'll notice that your Grand's body roll will have increased during turns and in curves. All you have to do is stay off the "go pedal". Lots of people seem to drive their SUV's like they're sports cars. That's dangerous enough stock. Add a lift and you've more than doubled your chances of rolling in a turning or lost control situation that could be just "scary" at stock height. Now I am definitely not trying to scare you away from lifting your truck! You'll just have to think about how careful you are now, and then be triple careful. You'll be a good bit more stable with a 2" to 2.5" lift compared to a 4" lift. Now I know your probably thinking "this guy is a sissy", but from the time I bought my 2000 Grand in Aug.'05, I could not wait to get it lifted. I finally convinced my wife to let me lift it as a Christmas gift to myself, and on Christmas Eve '05, in my garage, it took me about 45 minutes to add 2" in the rear and 2.5" in the front. Now it doesn't look like the front fenders are sitting on the front tires. And I had tires two sizes up from stock on it, with no rubbing, before I lifted it! This posting has become huge, so I'll start another in just a little bit! - dixiecrawler Replies to this message: jeeper96 (Jan 30, 2006 7:09 am) venturmax (Jan 30, 2006 1:44 pm) trickster (Jan 30, 2006 4:29 pm) and 1 more... dixiecrawler (Jan 30, 2006 7:45 pm) dixiecrawler (Jan 30, 2006 9:29 pm)
