Auto park replacement

I am familiar with the auto park system on an early Chevy P-30 chassis. Does anyone know what system is on a 2009 Workhorse chassis and how it differs from the earlier auto park system?

About 2003 the J71 auto park brake was replaced with the J72 version which was a complete redesign and a more robust system that did not see the same failure rate as the J71 version.

Knowing what chassis you are looking at (P30, P32, W18, W20, W22, or W24) and the year of the chassis (which might not be the same as the RV) would help to determine which transmission is in the RV and if the auto park brake was used.

It is a 2009 MH on a W22 chassis.

Thanks Mike but I am going to look a MH on the WH chassis on Sat. Yeah Roger helped me a lot with my auto park also.

It depends on whether the 2009 has the W22 or the W24 chassis...the W22 has a conventional foot parking brake (my gasser did) ...but it is totally a completely different system..
