Converter stall check

[MT71c-10]

Yea advanced untill I started hearing a ping then backed it up a tad. Converter guy is out of Idaho, I'm still trying to dig up the info on them.

All my receipt says is 9.5" high stall GM torque converter $369.00

Was purchased through a reputable tranny shop here in town. I'll go in tomorrow and find a little more out.

They really f'd up if a 9.5 inch converter is only foot braking to 2200rpm. Normally would use a 10 inch converter in that stall range. That cam is going to like as much timing as you can give it. What fuel are you running?

[MT71c-10]

I'm pretty sure all we can get here is 91, that's what I run. I'm pretty sure they run some ethanol in the blend here in the winter, but the same problems exist in summer. I would think aluminum heads would give a little room to play.

I'm going to pull the timing cover off here soon and triple check my timing, TDC, and put on a new timing chain set.

I'm also a little confused about the converter, I thought they told me it was a 10", but when I ordered it I gave them all the info, cam card, weight, gearing, etc. I wouldn't think any one would build a converter in a 9.5" with that low of a stall either, I would think it would just be a loosened up stocker.

It's $175 to restall through them. I don't know if i can trust them. Will other converter company's touch other manufacturers product?

Is there something in my trans that would cause this to happen? I wouldn't think so, It would just be slipping if it were on it's way out right.

When I changed the converters, oil and filter looked and smelled clean.

No its definately a converter issue. Your exactly right the transmission is either going to engage when the converter "locks up". Nobody else is going to touch that converter. You can get a boss hogg unit for around 400 bucks that will have torrington bearings and an anti balooning plate which should be in any converter in a heavy truck with high hp.Anti balooning plates are listed as a neccessary item for nitrous but getting a heavy vehicle moving stresses the converter the same way so its just some insurance.I personally wouldnt trust them at this point. If they didnt deliver what they were supposed to the first time whats to say it will be right the 2nd time. Im sure they will give you the bs line about theres always some variance in converters and we cant exactly guarantee stall blah blah blah..... so i doubt they will do anything without you paying for it. Generally a 2200 stall is an 11 or 12 inch converter as you said. 11 inch will go to around 2500 stall.

POOP! I'm going to call the tranny shop and get the name of this place, and ask a few questions.

Thanks for all your help cableguy, much appreciated.

Places on ebay are selling the boss hogg stuff for like 300 bucks and summit has the tci stuff.
