Mauisnow13 Posted July 11, 2008 Share Posted July 11, 2008 I am seriously considering buying an Auto V8 Z that I have found. The one thing that throws me off is that when you are stopped and shift into reverse and drive, the car kicks quite a bit. The seller tells me that they have put in an aftermarket performance shift kit and that is what is causing the kick. Does this seem right or do you guys think the tranny is almost gone? It has a chrysler 3spd tranny. Quote Link to comment Share on other sites More sharing options...

Mauisnow13 Posted July 13, 2008 Author Share Posted July 13, 2008 Good point. I found that the performance shift kit installed could definitely cause the car to kick when put into gear. From what I know, the shift kit allows less clutch slip in the tranny and so the gears grab faster and more noticeably. The kit is also supposed to make the tranny shift harder and faster so a kick when shifting into gear is a result of this. Is this correct?

dr_hunt Posted July 13, 2008 Share Posted July 13, 2008 Depending on the shift kit and who built the trans. The shift kit can, and most do, raise line pressure and have enlarged holes in the separator plate that will allow for quicker shifts which include first and reverse. When the trans is rebuilt performance the wavy steels are often omitted and replaced with an additional clutch or steel or both, sometimes requiring machining of the piston depending on the trans and thickness of the steels and clutches. This also contributes to the jerky feel. So yes, IME that is what normally happens when a shift kit is properly installed and the transmission is properly buit. It is a good thing in terms of slippage, hp handling capability, heat generation, as there is not enough hp and tq at idle to tear anything up. Well, unless your running a blown nitro engine idling at 2800 rpm. Quote Link to comment Share on other sites More sharing options...
