700R4 Planetary 1982, remanufactured and ready to install. Fits the 700R4. Ships fast from the USA.
Pulled the gear train out of a 700R4 from a C10, K5 Blazer, Suburban, Camaro or Corvette and found a front planet that whines, has pinion play, or shed metal into the pan? This listing is a complete front planetary set built around a 5-pinion carrier, remanufactured from OEM GM parts. It fits the 700R4 from its 1982 introduction onward and the 4L60, 4L60E, 4L65E and 4L70E that share the same gear train layout. Each carrier is washed and checked for pinion gear play; any carrier with play is rebuilt with new pins and bearings, or rejected.
The 700R4 gets its four forward gears and Reverse from two simple planetary gearsets tied together, a front (input) set and a rear (reaction) set. Power from the input housing clutches enters the front set, and its ring gear hub ties the front set to the output side of the gear train. Depending on which clutches and the band are applied, the front set either reduces speed together with the rear set or turns as a unit. The front set carries load in every forward gear, which is why a worn carrier usually shows up as noise and debris long before a gear is lost.
This set includes:
A five-pinion carrier spreads the load over one more gear than the four-pinion design, which is why it is sold as the upgrade for both stock rebuilds and higher-torque builds.
Road speed whine can also come from a converter, pump or the rear end, so isolate it first. A pump whine changes with engine rpm in Park and Neutral; a planetary whine follows vehicle speed and changes with the gear. Our 700R4 pump failure guide covers how to tell the two apart. Once the unit is out, inspect every pinion for side play and rough rotation, and look at the sun gear and ring gear teeth for pitting. A broken sun shell or worn thrust washers usually travel with planet damage, so see 700R4 common problems and fixes for what else to check.
Our listing title reads 1982 because the part fits from the first-year 700R4 onward; it is not a 1982-only part. The set is listed for the 700R4 and the 4L60, 4L60E, 4L65E and 4L70E. GM revised parts of the gear train over the years, and a Sonnax gear train article notes that a 2007 update to the rear (reaction) carrier, bearing and shaft means those three must stay matched as a set. Mixing parts from different design years can give wrong end play. Compare your old front carrier, ring gear and hub to the photo before you install, and if you are unsure, send us your year and VIN.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The set fits from the first-year 1982 700R4 onward, plus the 4L60, 4L60E, 4L65E and 4L70E with the same front gear train.
The 5-pinion front planetary carrier, front ring gear, front ring gear hub, front sun gear and both bearings for the set.
It is remanufactured from OEM GM parts. Each carrier is cleaned and checked for pinion play; any with play is rebuilt with new pins and bearings.
A whine that follows road speed, pinions with side play, and bronze or steel debris in the pan. Inspect the carrier with the unit apart.
Yes. Bench-check the gear train stack at about .020-.030 in., then confirm input shaft end play of .005-.035 in. after assembly.
