You can test the lo-reverse clutch by putting the tranny in 1st gear and get the speed upto around 30 and let off the throttle. If the lo-reverse clutches are good, the engine should brake hard the truck should slow down quickly. If it feels like neutral, the lo-reverse clutches are gone and a rebuild is necessary. Other possibilities are: worn/cracked piston seal (lo-reverse or reverse input) sticking lo-overrun valve reverse input clutches valve body sun shell (when it goes, no 2nd, 4th or Reverse) //2000CAYukon |
