Anyone having problems with 3-4 shift with JMod
This could just be a fluke, but I have heard a few reports of the JMod adversly affecting the 3-4 shift. I believe the trans in question was a 94 4R70W on a 3.8L V6. The complaint is that the 3-4 shift flares, and he has to let off of the gas for about 3 seconds for it to catch. In other words, it free-revs for about 3 seconds before the OD band kicks in. He claims a mild setting on the Mod.
Has anyone alse experienced these problems (other than those who didn't get their OD band properly attached)? Or is this just a worn out tranny that was modded?
If this is a reoccuring problem, I want to avoid modding my freshly rebuilt to the point that this occurs - probably altering the holes sizes to minimize this behavior.
If so, what OD piston do you have?
What settings did you mod your plate to?
