hi i got a voyager 3.3 auto with a 4speed 41te(a604)tranny and i lost reverse all of a sudden,drives forwards ok,i have changed the fluid and fitler and i have removed and cleaned the valve body, i have had a scan and no codes where pulled, the only problem seen was that the input rpms when in reverse and idleing were about 650 and it should of been 0 (like when it was in drive), all the clutch packs were change 2 and a half years ago approx 6000miles a long with the geartrain, 3rd gear carrier, seals and gaskets. anyone got any ideas???

Yes. The Sun gear is stripped or fractured. Also known as the planetary gear. This requires a complete teardown and rebuild.

Sometimes this happens when people get stuck in the mud and start pulling the old game of trying to shift rapidly from reverse to drive to rock the vehicle out of the mud. This trick will destroy these transmissions in very short order.

had that changed 2 & half yrs ago (6000mile), if it was the sun gear, i guess it would of made a noise and metal pieces would be in the pan!!??, but, there was no noise and just very fine paste like stuff on the magnet. it just stopped, also when in reverse, when i rev it up and then again it backfires.
