700R4 Planetary, remanufactured and ready to install. Fits the 700R4. Ships fast from the USA.
Tearing down a 700R4 out of a Chevy C/K pickup, Blazer, Suburban, Camaro, Caprice or Corvette and finding a front carrier with loose pinions, blued needle bearings or a ring gear that has been chewing on itself? This is a complete remanufactured front planetary set for the 700R4 and the 4L60 family that followed it, built in the thrust-washer style. It is the budget way to replace the whole front gear group at once instead of mixing a fresh carrier with a worn sun gear or hub.
The set includes four pieces:
The 700R4 builds its ratios from two simple gearsets that work as a pair: the front, or input, set and the rear, or reaction, set. The input housing clutches feed the front set, and the front set is splined into the output side of the gear train, so it is loaded in every forward gear rather than only one. That is why a tired front carrier usually announces itself with noise and needle-bearing debris long before it actually lets go. Because the pinions ride on needle bearings, heat and dirty fluid wear the pins and rollers first, and once the pinions can rock on their pins the gear mesh changes and the whine starts.
Drop the pan and look before you pull the transmission. Steel glitter mixed with needle rollers points to the gear train; dark friction material with a burnt smell points to clutches or the band instead, and a 700R4 with a misadjusted TV cable can cook the 3-4 clutch without the gears being at fault. Our 700R4 common problems and fixes guide walks through which failure leaves which kind of debris. On the bench, rock each pinion on its pin and spin it by hand; any roughness or play means the carrier needs bearings or replacement. Check the sun gear splines and the ring gear teeth for pitting at the same time.
This set fits the 700R4 and the 4L60, 4L60E and 4L65E units that use the washer-type front planet. GM also built a later bearing-type front planet, and the two styles stack up differently on the output shaft, so look at how your old carrier is thrusted before ordering: a flat thrust washer means this set; a caged needle thrust bearing means you need the bearing-type set. Sonnax points out that 4L60-family gear train parts went through several running changes and that not every piece interchanges, so compare your old parts side by side. If you are unsure, send us your year and VIN, or browse every 700R4 part we carry. If you want the heavier 5-pinion carrier for a built engine, see the 700R4 5-pinion front planetary set.
If the rest of the unit is tired too, a 700R4 master rebuild kit covers the frictions, steels, seals and gaskets you will disturb getting to the gear train.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The front planetary carrier rebuilt with new needle bearings, plus the front sun gear, front ring gear and front ring gear hub, all cleaned and inspected. Thrust washers and the rear planetary set are not included.
Washer type. Look at your old carrier: if it thrusts on a flat washer, this set matches. If it uses a caged needle thrust bearing, you need the later bearing-type set.
Yes, if your 4L60E uses the washer-type front planet. The front gear train layout is shared across the 700R4, 4L60, 4L60E and 4L65E, but running changes mean you should match the thrust style and compare parts side by side.
The thrust washers and bearings in the gear train stack, and inspect the sun shell splines and the output shaft. If the unit has high miles, do the clutches and seals with a rebuild kit while it is apart.
A Dexron automatic transmission fluid. Dexron-VI is backward compatible with the older Dexron grades and is the easiest to find today.
