I'm having trans and converter issues and trying to figure it out. I'm running a ford C5 with a C4 ATI full man VB.My new converter and trans worked awesome at first but lasted a few hundred miles until major slippage like 25% at the finish line. I replaced the converter with a used one and it seemed better until a few miles again and shifted funny and seemed to slip but not as bad, blew fluid out the vent at the track,so i removed it all and just tore the trans apart to find nothing wrong other than fine metal filings and a old hard servo seal. The converter is going back for inspection as i think the stator has issues. One thing i noticed is the stock pinto converter i replaced original custom one with has .075 smaller converter pilot to the crank and it's .200 longer and i think it's to loose and possibly from a 2.0 ford not a 2.3 like i have and is too small? would this cause problems? Just trying to find a solution as both my converters are full of crap and possibly trashed and the new trans needs cleaned and rebuilt. Thanks much!
