Gen 3 A/T slipping?
Anyone else get a "slipped clutch" feel on the A/T box when driving pretty gently. Usually only notice between 2nd and 3rd (i think)...

Anything to worry about, everything else works great.

Any thoughts?

Mac,
Is it a recent change you are experiencing?
Or are you just "wondering" in general?

Re: Gen 3 A/T slipping?
Im not sure, ive only had the vehicle 7 months, but seems to be more noticeable recently.

My big concern is that the motorplan is coming to an end very soon and if there is something wrong, i'd rather have Mits pay for it :)

I havent driven any others so maybe this is normal?

Firstly you must make sure they are aware of your concern, and they get the opportunity to check it out and comment.

Normally they will be happy to do it, as they will still get their money from the insurer (MMSA, I presume).

Hi

I experience the same "slipping" between 2nd and 3rd when driving gently. My vehicle has 135 000km on clock and I do quite a bit of towing (Explorer caravan). It is more pronounced when the vehicle is cold and less so when nice and warmed up.

I have not experiened any trouble in all this time.

As soon as you accelerate a little faster the "slipping" disappears.

Hi Mac,

Is this a problem your facing in any driving conditions, or when slightly under load.

When I bought my Pajero, my Mackie took me with it on a semi steep incline, and then watched the rev counter,
You couldn't really feel anything, but when under load, i.e. going uphill or towing, it would go into 3rd, and then with no noticeable feeling or sound, the needle would dip by 200-500rpm.

This slippage is definitely not normal, and will get worse after time, as mine did.

I had my gearbox re-done, including replacing a lock-up solenoid that didn't work properly (this could actually be the problem - lock up kicking in prematurely and not to the extent it should)

Since then the gearbox runs like a dream, and with the lock-up solenoid working properly, my fuel consumption has increased by about 2L/100km, that is, until I put the roof-rack on.

I think youve got this spot on with what im experiencing. Mine is exactly the same.

Has yours always done this?

Hi

Yes - mine has done this since new. I have not had any trouble whatsoever. It tows like a dream and I would think that if there is a problem it would show up under serious load like towing.

I liken the gear change to driving a manual car slowly and changing to a higher gear when your speed is too low - you then have to slip the clutch a little to make a smooth gearchange. The autobox is doing the same.

If you accelerate slightly faster it disappears immediately.

I would'nt do anything except mention it to the agents to check until you experience some other problems as well
Re: Gen 3 A/T slipping?
i wonder if im experiencing the same thing?

Had my 90k service done at Mitspro last week. Asked them to check the ATF and change if necessary, which they did. After about 400km of trouble free post-service driving, the status changed. While accelerating my engine now sounds like it's surging and lagging, as if i were applying and releasing pressure on a clutch.

The effect on the momentum of the car is negligible, and the rev counter doesn't report any discernible effect, but the sound is definitely one of the engine revving and dropping and revving and dropping in each gear.

It goes away as soon as I plant the accelerator in the carpet.

Taking it back to Mitspro at Sparrows-flatulence tomorrow. Will give update as soon as i know what's going on.

Re: Gen 3 A/T slipping?
I also experience this on my gen3 Di-D auto but only at constant throttle on certain uphill gradients.

In 4th and 5th under certain conditions the torque converter will lock up and disengage in about 10-15 second gaps.

Going to tiptronic sometimes help but I have learned to either back off or accelerate to eliminate it.

I think it's normal for the autobox to do this with fresh oil (mine was also flushed recently)

I must also admit that the torque converter is only starting to lock up properly now after over 10'000km on the fresh oil. Probably took some time to clean all the old gunk off the clutch plates.

Ask them what oil they used. If it's not the behaviour like mine described above they may have used the wrong oil. The mitsu autobox is VERY fussy over what oil is in it. If it's the wrong or old oil it will operate in funny ways.
