Re: mach 1 autos

From what I understand, our torque converter in the automatic can't handle 7K.If you want to improve your shifts, a tuner can firm up your shifts and shift points, I did that.7K shift point , I would'nt.If I was gonna race my stang, I would get a Darrin converter,he's a member on this forum and I hear nothing but good things about his products.Do a search and I'm sure he'll pop up.Good luck.............................Kevin

Re: mach 1 autos

It isn't the converter (altho the stock converter is too weak for a power adder) the weak link is the spiral lock ring that is behind the pump. If you use Darrin's modified ring assy you can rev it faster than the engine can handle. While you are in the tranny changing that you might as well change the OD band and the pump seal.

Re: mach 1 autos

When I had Darrins Converter installed, I had a improved Spiral clip installed. The original clip was already coming outta place..
