78 Dodge Apollo Transmission issue

[gica]

Something weird happened on the tranny last week. I sort of let someone live in the RV and I did notice that he didn't fully stop the RV before shifting either in Drive or Reverse depending on the case, so the guy calls me that the RV does not go in Drive or Second anymore. It does shift if started in First then manually shifted to Second and then Drive. I remember that in cars it had a governer(or something like that) that handled the shifting. This tranny was rebuilt not too long ago so I don't think it's slipping from wear. I read somewhere that the forwarding band is broken(that was on a truck tranny do these have it?). Any ideas on what's doing it? Thanks in advance.

First thing to do is check the fluid level, and condition. Look for any hint of browning; instead of red ; of the fluid or burnt smell.
The trans in your unit is the same as the trucks of the same year, first gear is a clutch pack, second a band, third a clutch pack, and reverse a band. If you break a band, second or reverse, you loose that gear , regardless of how you shift it. Governor problems usually effect upshift not engaugement problems, the valve body, the hydraulic brain of the trans may need repair if fluid levels aren't your problem.

Thanks Skip, this RV if I'm not mistaken has the 727 tranny and I was reading that the governer being stuck can cause such thing as not being able to upshift, also 2-3 valve being suck can cause the engagement problems. Found this for the respective tranny reference http://www.allpar.com/mopar/transmis...-tom-hand.html
