Question about 2001 Mitsubishi Diamante

1 Answer

Transmission changes slowly

I have a 2001 Mitsubishi Diamante LS. The car runs good but when I tend to change the trans lever from drive to reverse it takes me about 3 to 4 seconds before it does so. However, couple days ago the time was very cold and I notice the transmission was very quick to move off when I made the change from drive to reverse. What could be the problem.

    Thanks for the info Technopro. I was thinking on the same line, because oil tend to get thicker because it is cold and when its warm it more it has velocity (thickness). However, where can I get the real transmission oil for this car. You also said to flush, but is changing the oil the same as flushing? Thanks.

When it was cold weather the oil is thicker and definitely here the transmission needs a good flush. Be careful to use the genuine Mitsubishi transmission oil as it was designed for it.

    The flush consist of using a machine to force the dirty oilout and refilling it at the same time and thus ensuring that the torque convertor(which holds lots of oil) is flushed too.

    I recommend to see your local dealer parts channel to get the approved oil.

Car has a slight delay in drive and reverse

No. Traction control measures the wheel spin which happens after the car is underway.

What you describe is thick fluid, low pressure in the Torque converter, delayed engagement in the Torque converter, or sticking valve body in the trans.

If you have a trans Warranty, this is something you would take in to correct.

Adding transmission fluid to my 2001 Lincoln LS

Have the car on, in park, emergency brake on. Under the hood, red dip stick. From line to line should be 1qt. This is best done when the cars warm. Add until the 2nd line. Get in your car, hold the brake, slowly put it in reverse, neutral, drive, 3,2,1 then 2,3, drive, neutral, reverse, park. Repeat a couple times to move the oil around, and you're good to go.

Where is transmission filter

Hi there,

The Diamante transmission can actually have up to 2 filters - one internal & one external.

It is recommended to change both these filters when doing a transmission fluid change.

ONLY USE MITSUBISHI ATF - Do not use any other brand of fluid, or you will cause damage to the transmission (Mitsubishi fluid has special properties).

The internal filter is inside the transmission casing and is accessed by dismantling the trans casing - careful, as oil will escape from the trans when you remove this cover. See item # 29, in picture.
The external trans filter (miniature version of an engine oil filter) is mounted on the transmission body, which is located behind (or under) the battery compartment. See Item # 6 in picture.

Will not move but starts

the diamante is a front wheel drive car,if it does not move ,you probably have a bad transmission ,turn on car with cold engine in neutral ,check fluid,make sure fluid reads at cold level on dipstick,if fluid is all right sounds like you have a bad trans-good luck
