Its worth a try, the shift kit is just some plastic dowels, you could easily just make one, take apart the accumulators and place the dowels on the rods,( it just limits accumulator piston travel) I could scan and email instructions as to where the dowels go. i personally couldn't believe i paid money for some small plastic dowels , but it worked for me. i find that the tranny only shudder shifts when hot in stop and go driving, i have a tranny cooler albeit a small one, I want to get my fans to turn on sooner but discovered that this is controlled by the PCM. I could wire in something but that's a lot of hassle. Could get the PCM retuned to turn on fans at a lower temp. (overkill Motorsports) Maybe i'll install one of those tranny coolers with a fan from B&M. the real fix is a rebuilt trans from a specialist like triple edge performance,
