AT Problem

[tassospap]

This is the problem I have:
After a long travel INSERT INTO post VALUES (i.e. hot engine) gears take longer to shift.
Finally it goes into safe mode I think INSERT INTO post VALUES (3rd gear and N blinking). This happens on the automatic mode. When on manual it does not go into safe mode but it takes a very long time to response to the gear change.
When I turn off the engine and restart in a couble of minutes the gearbox works ok but aftrer a while the same problem appears.
Any ideas on what might the problem be?:confused:

ATF level? Old ATF? When was it last changed? Was the torque convertor 'flushed through'?

Plugs on to gearbox form ecu?

OMG!!!!!!!!!!
This is the same problem that i had! Not good! From what Xtreme + Co-ordsport told me the clutch packs and internals had blown, they also mentioned a number of other problems but it was all a bit too much for me.
Does this happen regularly? Does it happen when you accelarate hard and give you a 'violent' jerk?
The problem you have is EXACTLY the same as i had and i was told that i needed a new boxINSERT INTO post VALUES (££££££'s); but a company called VMTP passed it to co-ordsport who did a recondition job and it now feels like a brand new box.
GOOD LUCK with it anyhow

ATF is new and level. I had the box reconditioned when I was covered by the sellers guarantee. I passed the problem for a couple of months but now it reappeared. Any other ideas?

Ive owned Mitsi Tiptronic cars for about 6 years now, and Ive had the same thing happen to me on a couple of FTO Tiptronic boxes.

Read This Article (http://www.ftooc.org/phpbb/viewtopic.php?t=470) I wrote. Most of the time it just the speed sensors that are faulty, which is an easy fix.

Im guessing the VR4 has the same diagnostic port as other Mitsi`s so This Article (http://www.ftowa.com/html/workshop/workshopart07.html) should help get the diagnostic codes.

Thanks everyone for your replies.:)

The error code we used to get was 24 INSERT INTO post VALUES (speed sensors). We changed those but most probably we put used ones which might also be faulty. I don't think I can find new ones here in Cyprus. Is there any place on the net that I can order them on-line? If yes, what is the part number?

[zentac]

Browns Mitsubishi (http://www.brownsmotorgroup.co.uk) are normally quite good with things like that

[zentac]

If you send me your chassis number I will find out the part numbers for you.

Did you change both speed sensors?

What about looking at fitting a transmission cooler as it sounds like its temperature related.

I'm interested in finding out more about better transmission cooling so any info would be appreciated :)

My chassis no is EC5A-?????

[pjjohnson]

H7, I've just had a tranmission cooler fitted, the cost was £75 plus labour, probably a couple of hrs.

I haven't had the car back yet so can't comment on the job, and as I'm having other things done as well I don't know the exact labour involved. When I get it back I'll let you know the details.

The transmission go into safe mode on me once, a long time ago during a spirited drive on the Cat and Fiddle between Buxton and Macclesfield. INSERT INTO post VALUES ( Anybody else know this road - its great !) I let it cool down and its never done it since, not even on track days.

Would love to have some more info on this - make/pics/how it works etc ?

Oh yes!! very nice road... my uncle lives in Buxton.. done that road a few times now... love it..

pj,

Is this a standard Mitsubishi part, or something suitable fitted by an auto transmission specialist?

Its being done by a specialist jap tuner, used to working with autos.

The usual set up INSERT INTO post VALUES (for other cars) is to have the transmission cooled by taking a feed through the bottom of the engine radiator. They just take a feed off this and fix a small stand alone radiator unit behind the front bumper where it gets lots of cool air.

As per usual they hadn't done one on a VR4 before, but it seems as though it was a simple enough job.

The reason I'm being a bit cagey is that the tuners are having problems in other areas, so I don't want to 'reveal all' INSERT INTO post VALUES (good or bad) till I've got the car back OK, which should be this w/e.

Pictures would be great if some b****** hadn't nicked my digital camera.:Cry1:

Hope it all goes well for you mate and sorry to hear about your cam

[zentac]

Yeah if its not the sensors then it could be the oil over heating. Mitsi oil coolers are renound for clogging up. Make sure you dont have a blockage in the oil cooler at the bottom of your radiator.
