I guess TH700s need to be beefed up to handle a shift kit. I'm surprised mine has gone 136,000 miles with no problems. Of course, I can hit 80mph and still be under 2000 rpm! I hit 85 mph and I'm at about 2150rpm. At 65 I'm only at 1400.

But it STILL gets 10mpg! This 305 is getting tossed soon. I was beat by a F*rd diesel yesterday!
