Hi - travelling on highway felt bang, shudder. Pulled up thinking blow out. Tyres good, engine restarted but not engaging. Short story - trucked back to mechanic , auto trans pulled out and wow looks like someone has thrown in a grenade. Will try to attach photo of ring gear/flex plate. The convertors nozzle that fits into the centre hole is also mangled. Am told that a new torque convertor could cost up to $3k. Mine has been sent to a company that reconditions them. They claim that this is not a rare occurence. Not an expense that I am looking forward to. Does anyone have any idea what would cause this or how it could be avoided? Only done 167,000 km.
Sorry can't help you on why or how it can be avoided. I'm sure a good auto transmission specialist, would be able 2 answer you question if know body on here can.
Out of curiosity what company did you sent the gearbox 2?
Cheers
Todd
Time is never wasted when your wasted all the time
I have seen similar things caused by dodgy engine conversion adaptor plates .
be worth checking everything lines up perfectly surely they will balance and true the torque converter when they repair it.
Sure Todd, I will post when I catch up with the local mechanic over the next couple of days. The Company is in Adelaide. My mechanical knowledge is terrible - is the torqe covertor the gearbox or is it only one component of it ? The componet they showed me looked like 1/2 of a very big football with a very damaged knob on the end of it. Cheers
Hope so. I have no idea when it comes to things under the bonnet. Great question to ask them when I next call around and see how they are going. I have had this vehicle since new so no one should have played with it.
The torque convertor is only a component of the transmission, equivalent to a clutch on a vehicle with a manual tranmission.
As stated before, the failure could have been caused by imbalance, something out of alignment, incorrect torque (too loose or too tight) or even just a weak flex plate. They do put up with a lot of stress and vibrations, especially diesels!
Reconditioned torque convertor is the way to go, new is definitely not worth the extra expense.
