Symptoms of Converter Failure? Hey guys, posted this in the Auto tranny section and got no replies, figured maybe you could help me out here.
Thanks for any help, much appreciated! 
One of my buddies thinks he's havin issues with his verter. It's a turbo 400 with a yank verter. Used to go to 5000 on the t-brake, now it's seein 5800 - 6000. Only problem is, he just moved from florida to north carolina, the car is running like a pig, don't know if it's the conditions there, or something going on with the verter, what are some things to check to figure it out before having to just pull it and send it in to get checked or is that the only thing you can do?

Might not be much help Devon, but when the car starts varying in et's and stall speeds change, that means she needs some help. Changing tracks adds another element, but you'll know when the convertor needs a fresh rebuild. How much time and/or passes?

I'd say he's only had it in there for a year tops, and probably at least 75 - 100 passes maybe, not fully sure.
It could possibly be that the car is making more power at closer to sea level and the converter needs tightening. We have also noticed that the car gets real inconsistent when the converter starts slipping. We also watch trans temp. that is another sure sign of trouble when temp goes way up.

interesting topic, i am wonding this too. my daily driver has been acting weird lately. like the tranny is slipping (but it's brand new) but it still has the 95k mile stock converter in it, but under a 60%+ throttle it still shifts nice and hard. just doesn't pull like it use to, and at slow speeds seems like its almost slipping, or just really under powered.
