    Reconditioned Torque Converter

    Hi guys,

    After a bit of research on this forum, I have come to the conclusion that my NM has a stuffed torque converter. Have tried doing a tranny flush, adding dr tranny etc....still have the "shudder."

    I am now in the predicament...I got a quote from Wholesale Automatic Transmissions for one of their "Heavy Duty" torque converters (just the actual converter). $1250.

    And another quote for a reconditioned torque converter for $350. (with 12 months warranty)

    It is very tempting for me to go the cheaper option....but would I stupid to do that? Are the reconditioned torque converters any good? Is it going to cause me more problems down the track?

    All opinions would be greatly appreciated.

    I gather you tried genuine MM fluid in it? It fixes most of the shudder complaints. I have no idea on the reconditioning process, but I do know they cut them apart around the outer rim and then weld them back together to do so.

    Do you tow much and if so is it heavy? If so the HD version might be a better bet.

      Nothing wrong with reco torque converters. Put one in my XR Falcon mid 70's and it's still going strong with the same converter.

        Hi tmyers,
        Have you had confirmation from an auto tranny shop? Also as someone already said, did you use only genuine MM auto oil for the flush? It matters.
        You can get a shudder from the rear diff too, if your diff is like the NL, but that was easily remedied. Never have I had the auto shudder but just thought I would mention this. Cheers.

          Yes, I did use genuine SPIII ATF for the tranny flush.

          Have not got the confirmation from an auto tranny shop, but have had a diff specialist take it for a drive, and he reckoned it was the torque converter.

          Sometimes it does feel like the vibration might be coming from the rear diff though? Is this a completely different problem?

            If you are going to tow you better get the 'fixed version' from Wholesale or you may be doing the job again. The stock converter isn't up to towing decent loads.

              OK then. I'm sure the diff guy would not have passed up on a diff job if he was not sure the torque converter is the culprit. The diff shudder I had only appeared under firm accellaration from a standing start and not when going straight but when turning, like from a fuel stop driveway, to get into moving traffic. Different oil with additive and it's gone. Sadly, it appears your shudder will be more complicated. Good luck.

                I do have a camper trailer which I only tow every now and again. Its approx 700kgs dry weight, so prob bout 1 tonne once loaded.

                I was wondering after the torque converter has been "reconditioned" do they make any changes to them to become a little more suited to towing?

                  My shudder is only appearing after I get over 80km/h and under acceleration.

                    My shudder was in 'over run/over drive'. So if in top gear at 60 and try to accelerate a bit gently with low revs it would shudder like mad.

                    MM said they thought mine had a stuff TC, but they found a service note/bulletin thing that said this was a known issue in this car. They changed out the fluid and the problem has been gone for a couple of years now.

                    Its in for another auto service on wednesday i can ask them to check my history for the service bulletin number if you want?

                        Be careful spending money on the torque convertor.

                        I was convinced my problem was the torque convertor, got an upgraded TC fitted and still have the problem. The reason I was so convinced was that it vibrated under load when the TC locked in. That was around 100kph in 4th. If you get over 120kph it will happen in 5th as well. I first noticed it towing up a steepish but fast flowing range. (Corners weren't that tight so you could keep the speed up.) It was in 4th of course but under full power. So it didn't work. I am currently looking at replacing the drive shaft bush. Refer to link http://www2.pajeroclub.com.au/forum/...h+shaft&page=3

                          Thanks smoothsearcher.

                          I have it booked in next week for a torque converter replacement. Will definately get them to check the tail shaft bearings (bush) before replacing the TC.

                          Is there an easy way to distinguish whether it is a TC problem or a tail shaft problem.

                          People on the forum have described the TC problem as a shudder, and seems as though the tail shaft prob is described as a vibration. What is the difference between a shudder and a vibration??
