3.2 did Transmission problem

Mon Aug 13, 2018 5:00 pm

Pajero 3.2 Did automatic (2005)
340ks on the clock.

Suddenly we are experiencing a bad gear change from 2nd to 3rd accompanied by a knock. When changing gears it seems as if the engine is experiencing an excessive load.
I changed the transmission oil via the correct procedure of pumping the oil out whilst the engine was idling, it took 30 seconds, I the dumped the remaining oil by removing the transmission pan. I replaced the filter and filled to the correct level with Diaqueen Sp III from Mitsubishi. The problem still persists.

A reputable gearbox company said there was a Transmission failure We replaced the complete Transmission (which included the 4x4 transfer unit) this replacement Transmission has only done 150K kilos. The problems still persists!!

Another reputable dealer said it was the back diff mountings. Rubbers/bushes were replaced and still the problem persists.

I have noticed the following symptoms:

• When I change from P to D or R the engine revs up by 200 rpm, it seems to jerk into gear, it never did this before the issue started.
• The Transmission does change up and down however the 2nd to 3rd gear change is violent.
• No signs of overheating, engine or Transmission.
• The transmission will do same in auto and tiptonic.
• If I floor the accelerator it seems to change better.
• Once the car is in 4th and 5th it runs like a dream!!!

I’m sure it is sensor related and the last thing I want to do is dig out the ECU!

Please any assistance will be gladly appreciated.

Gen 3 Transmission problem

Sun Dec 30, 2018 2:53 pm

I was just going to start a similar thread, but came across this one.
Having almost the same symptoms.

Mine is a 2001 3.5, I suppose its the V5A51 transmission, but symptoms are the same.

Since I bought my car (drove 70K in 6 years with it till now) it sometimes had a problem in taking several seconds to engage into R or D at the first run, and mostly engaging with a hard bump. This is mostly noticeable in cold mornings, as soon as the transmission warms up a little or in summer there is no problem.
I researched about the problem and assumed it is something called sticky valve, where a valve gets stuck and while building up pressure it opens abruptly and hence the bump. When it warms up it moves freely.
I changed ATF (Mitsu SP3) twice since then, first time with the filter and nothing changed.

I was living with it this way avoiding to open the trans for bigger repairs, till this week another similar problem occurred, but when shifting to 2nd.
When its time to shift to 2nd the car brakes itself, one time even so hard that the rear wheels blocked as if I have pulled the hand brake.
Its like trying to go into gear and couldn't, after 2 sec of braking it returns to 1st again. after several trials either it has warmed up and start working normally, or it forces itself into limp mode and drives on 3rd till I turn the engine off and restart.

As soon as I drive less than 1 km it is already shifting as it should.

Changed the whole ATF to give it a try, although it has been changed only 16K Km before. Th fluid came out dark brown, even darker than the previously released fluid that had made 50K.
I flushed the system and poured in fresh fluid, but nothing changed.

Any advice where to look for ??

Hi all, I noticed this thread some time ago and I was experiencing similar symptoms on my 2005 GLX.

After about 300 000Km I sometimes started experiencing a thud when changing from N to D. It would come and go. Then after 320 000Km engaging D from N the box sometimes did not engage immediately (cold mornings), when it did it was with a thud. I was advised by a reputable Mitsubishi specialist to replace the Autobox oil and filter. Another Mitsubishi autobox specialist advised against this and warned that the autobox would most likely seize (in his experience 65% do this at 300 000Km if the filter was never changed). He advised that I rather overhaul the autobox or just change the oil.

I took it to the first specialist who did not agree with latter. They did the oil and filter replacement. The problems were solved. After a further 2000Km the A/T Temp light came on and 40Km later the box seized. Stuck in D, 3rd gear, and N light flashing. Had to tow (prop shaft removed) my Pajero and had the autobox, Transfer case and all replaced with a second hand unit with 260 000km. She is now running perfectly.

Lesson learned: At >300 000km without ever changing the autobox filter rather overhaul the autobox it is cheaper. Or replace the filter every 80 000Km. P.S. I did tow a caravan during school holidays.

By the way, I was in Kruger when the autobox cooked.

New oil cleans all the gunk

If you renew the gearbox oil after such along haul, then change the oil and filter again after about a 1000km to get rid of the of the gunk that was worked loose..

You mentioned you were in the kruger. The auto likes to stay in third and work the TC hard which add huge amounts of heat to the ATF. If you are doing slow work for extended periods, use the tiptronic function to force lower gears and then even low range if needed.
