You are in the Mitsubishi Diamante
What is this discussion about?
Mitsubishi Diamante, Sedan

Here is the service bulletin info on the 1997 Diamante transmission:
MITSUBISHI DIAMANTE 1997
Service Bulletin Num : 97110123014
Date of Bulletin: NOV 01, 1997
Component: POWER TRAIN:DRIVELINE:UNIVERSAL JOINT
Summary: SOME CUSTOMERS MAY REPORT HARSH SHIFTING DURING 2-3 UPSHIFT.
Your dealer's service department should be able to show you the full text of the service bulletin.
The Mitsubishi Factory Service Manual is by far the best manual for do-it-yourself repairs. But, it will cost you over $100 from the dealer's parts department. You can get the best price by buying it though one of the many Mitsubishi dealers that sell at wholesale through www.parts.com, One such dealer is http://www.mitsubishiparts.com/default.php though you will have to contact them at 1-800-357-1892 to get a price on a service manual because it is not listed in their online store. Make sure you get a quote for a service manual, not an owner's manual.
As to aftermarket, the only one I know of is the Chiltons at http://www.amazon.com/exec/obidos/tg/detail/-/0801993156/qid=1069- 699831/sr=8-1/ref=sr_8_1/103-0008596-4117434?v=glance&n=50784- 6 It is nowhere as comprehensive as the Mitsubishi manual, but it is under $20 and will give you a lot of what you need for doing your own service.
Probably the most accurate review of the 1997 Diamante can be found at http://www.nctd.com/review-intro.cfm?ReviewID=338
#1029 of 1497 Need new steering rack??
Dec 04, 2003 (8:21 pm)
My power steering seems to be dying on my 98 Diamante. About 4-5 months ago, it started groaning and "grinding" when making wide or sharp turns. This, coupled with the tell tale drops of fluid on my garage floor suggested the power steering fluid. No, I've never had it flushed. The car has 100k miles on it give or take. The P/S fluid refill was bone dry upon inspection, and so I filled it and have since refilled it when I hear the noise. The results are usually the same - immediately stopping the groaning noise and steering becomes silky smooth...for a while. Then, the leaks and the groans come back in spades weeks later, sometimes days later. I had Mitsu Svc inspect it and they say I need a new rack. There explanation for this was something like "these racks just start leaking when they get old. Or, it may have been damaged somehow". Ok. Apparently, these things are big money to replace (I had to sit down to stop from passing out at the cost) - about $800 something, and I'm not even sure if that includes tax. Assuming that it is the rack that is the cause of the problems, what if any danger is there in continuing driving this vehicle and replacing the fluid when needed? I've not had a problem (except the messy leaks) doing this (until I can afford the repair) ...until the other day, when I apparently put too much P/S fluid in the refill area; I have what I can only describe as VERY LOOSE steering, and an on again off again bizarre drifting type effect when I go into a tight turn at fast speeds. Replacing the tires didn't make a difference. Could the P/S rack or the fluid levels being undoubtedly maxed out be causing the weird drift? Thanks.

brought in the D for servicing today
sales dude informed me of new additional incentive for current mitsu owners....another 3000 off on Diamantes.
WOW, that's more incentives than GM even, hehe.
showed me an ad for a 29k list Diamante for like 19,000.
get it now......
I wanted to test drive the Lancer Ralliart, but they didn't have one. Took out an OZ rally and really liked the car.....very nice small car. Excellent steering.
#1031 of 1497 How bad is putting 87% gas in an 02 D ?
Dec 07, 2003 (12:02 am)
Well, lately my wife has been driving our 02 Diamante and recently she told me that she has been putting 87% gas in it. I realized that it does not have the same pick as before. Does it now need some fuel filter cleaning?
Also I have put on about 33K miles in less than 2 years and the 30K miles maintainence package costs $599 at the Mitsubishi dealerships. I don't want to spend that kind of money. What is the recommended service for 30K miles? So far I only had oil changes. I got a K&N air filter when the car had 15K miles and don't think it will need replacement.

i was checking that out yesterday, coincidentally
the dealer here had the 30k maintenance pkg. advertised for some absurdly high number like that.
WASTE OF CASH.
here was the primary bits i caught the most of it
chaeck belts hoses and brakes
lube some hinges and driveline parts
check driveline components
change plugs and air filter
and probably some other stuff
thing is, it didn't appear to me to be anything worth 5-600 bucks.
I'd think a non-dealer service center could do this much cheaper.
as far as the gas goes, an extra dollar per fill won't equate to much more than 50 bucks a year. a drop in the pan compared to your car payment.
better to keep the engine clean.
#1033 of 1497 30K maintenance package
Dec 08, 2003 (10:18 am)
The dealership here does a lot extra, like tire rotation. I believe that's $200 at Mitsubishi dealerships.
Thanks for the info. I think that anything over $150 for the services is too much. I could have done that myself but coolant and transmission fluild flush needs equipment that I don't have.
#1034 of 1497 Antilock brakes
Dec 08, 2003 (1:04 pm)
The antilock brake warning light is on steady and the traction control light flashes until I push the traction control off button then both lights stay on steady. Can you put jumper wire in the scan plug to obtain a code as to which wheel sensor is a problem? Where is this plug and what code should I be looking for??

I would only get the tranny serviced at the dealer. I just had the 30k tranny flush done for my 02 Lancer at the dealer for $150. My manual says the coolant only needs to be flushed at 60k (the Diamante should be the same here). The spark plugs are capable of lasting 60k or more with no problems so I would put that off to 60k as well. The rest of the "checks" are simply a money maker for the dealer. You can have them rotate the tires if you feel you need it, but that shouldn't cost more then $40.
Let me forewarn you though that Mitsu trannys are sensitive to the type of fluid used. I'm friends with my local dealer's service foreman. He said Mitsu will refuse to honor the powertrain warranty on the tranny should it fail due to using dextron fluid. Most quick lube joints use dextron, which is a thicker fluid then the SP3 that Mitsu uses. He said some trannys will operate ok on it and others failed after 10k. One guy was forced to go after super lube to get the tranny replaced because Mitsu wouldn't honor the warranty due to not using the proper fluid. With that in mind, I would either have the tranny serviced at the dealer or buy the fluid at a Mitsu dealer, make sure the shop uses that fluid, and keep the receipt. If you do go to the dealer, just specify you want the tranny service and that's it. You don't have to do the "30k package".

Do you know where I can verify this 3k rebate for returning Mitsu customers?? I'm currently semi interested in trading in my Lancer for an 04 XG350. The Diamante is in the same class and if they offer that kind of deal, it would make it easier to trade in my Lancer with negative equity as well as stay in the reliable Mitsu family. The only problem is, the other half really likes the XG's looks. We aren't sure if we want to waste the money to upgrade to a more expensive car when my Lancer has been flawless in build quality and reliability (OZ automatic). But the desire to have a luxury car is intoxicating.

ads in the paper here and also confirmed by a salesman at local dealer.
check with your dealer and also visit mitsucars.com
one dealer here has an 03 VR-X with 4k miles on it......if you would settle for lightly used its a great deal right now but no rebates. price is still cheaper than new. VR-X is sport version of Diamante.
Basically figure 9-10 grand off list for new Diamante if you have loyalty.
An XG is based on the Diamante anyways although in some ways has surpassed the Diamante. Either car is a nice car. XG is more traditional luxury cues.
You have an OZ, right? I tested a manual OZ on Saturday and really liked it for the 12k price it was selling at. New.No ABS on it tho.
