There are numerous CVI's, one for each clutch pack and for upshift and downshifts.
CVI stands for clutch volume index which means the computer has a built in spec for the time it takes to make a shift and when it takes longer to make a shift it will be high. High clutch volumes can indicate a clutch is worn, has a broken snap ring etc.
There is NO service bulletin from Chrysler with anything to do with the valve body or your problem. Most transmission shop subcribe to a transmission repair network where they can find info on how to repair problems that other people spend most of there day trying to do by modifying oem designs. These people do this to try and improve some of the oem designs that they believe are a flaw. This is where transmission shops get there bulletins from. The bulletins are not from Chrysler they are from other people/companies that try to improve the trans and sometimes they are actually worse by doing what these people say. If Chysler new there were flaws that would cause premature failure they would come out with a recall or technical service bulletin and revised parts to prolong life.
What codes are you getting from the transmission control module? Did they tell you?
Does your engine flare up when climbing a hill which indicates slippage, I do not mean shifting down I mean it stays in the same gear but slips and causes engine to speed up.
I hope this helps you! If you could get me the codes that would be great, Thanks for know, Richard
I am more familiar with All DODGE products then you think. The MLPP is not used in our terminology. There is no externally mounted shift lever position sensor. It is mounted on the valve body in the transmission and is called a Transmission range sensor. I am trying to help you get this repaired without getting screwed by the trans shop. Ask your shop what that stands for because it is called a transmission range sensor. I am an expert when it comes to these transmissions, I work on 2 a week and I know these inside out and can answer any questions you have about them. Please reconsider my help because I have been building transmissions for 20 years.
