T-0220-39 Master Transmission Bushing Driver Set 39pc

If you rebuild more than one family of automatics, you have probably driven a bushing with a socket and regretted it. A 4L60E pump bushing that goes in crooked, or one that ends up too deep, takes the converter hub off center and wears the new front seal. A reverse input drum bushing that gets shaved on the way in leaks oil the clutch needs. The T-0220-39 master set is 39 shouldered steel drivers that cover the GM, Ford and Chrysler units most shops see, from the 4L60E, 700R4, TH350 and TH400 to the C4, C6, AOD and 727, so each bushing gets a driver that fits its face and bore.

What bushings do in a 4L60E

A 4L60E does not have roller bearings at most of its rotating joints. It relies on bronze-faced bushings to center the shafts and drums and to meter oil to the clutches. The GM overhaul procedure lists bushing service at the case rear, the pump body, the reverse input clutch housing (front and rear), the input sun gear (front and rear), the reaction carrier shaft (front and rear) and the reaction sun gear. Every one of those is a press fit, and the factory procedure calls for a dedicated driver from the J 34196-B bushing service set on a driver handle. The pump body bushing even has its own position stop so it ends at the right depth. Those details are why a matched driver set pays off: the shoulder controls depth and the pilot keeps the bushing square.

Signs your rebuild needs new bushings

• Bronze slivers in the old filter or on the pan magnet, which the GM procedure flags as bushing wear
• Visible side play when you rock a drum or shaft on its support
• Front seal leaks that come back after a new seal, from a worn pump bushing
• Burned 3-4 or reverse clutches with no obvious pressure cause, where a worn bushing let feed oil escape
• Scored bushing faces or copper showing through the wear surface

How to decide which set you need

If your bench only ever sees GM rear-drive units, a smaller set will cover it: the 13-piece T-0220-700R4 set is built around the 700R4 and 4L60E. Buy the 39-piece master set when you also rebuild TH350, TH400, Powerglide, Ford or Chrysler units, or when you want drivers for the older and less common cases. Our 4L60E bench rebuild tools guide covers the rest of the bench kit you need for a 4L60E, including end play and spring compressor tools.

Fitment

The listing covers GM Powerglide, ST300, 125/125C, 180/180C, 200/200C/200-4R, 250/250C, 325/325-4L, TH350/350C, TH400, 425, 440-T4, 4T40/4T40E, 700R4, 4L60, 4L60E and 4L65E. Ford coverage is the A4LD, AOD, ATX, C3, C4, C5, C6, FMX, cast-iron Cruise-O-Matic and Jatco 3N71/4N71. Chrysler coverage is the 404, 413, 470, 500/518 main case only (not the overdrive section), 604E, 618, 640, 670, 727, 904/999, plus the A340, KM170/KM175 and ZF4HP. It cross-references the T-0220, T-0220-39 and KT300 #72367 sets. If your unit is not on that list, send us the transmission model before you order. GM rear-drive parts are on our 4L60E parts page.

Using the set

• Clean the bore and check it for burrs before a new bushing goes in. A burr will shave the bushing.
• Pick the driver whose pilot fits the bushing ID and whose face sits on the bushing without touching the bore wall.
• Start the bushing straight by hand, then press it with an arbor press where you can, or tap with a dead-blow hammer, until the shoulder stops it.
• Line up any oil holes or notches the way the original bushing came out, and check the depth against the service manual.
• To remove a worn bushing, drive it out from the far side of the bore with the matching driver, or collapse it carefully without scoring the housing.

Doing the rear of a 4L60E? The extension housing bushing has its own tool, the T-0160 tailshaft bushing tool. Bushings usually come in a full 4L60E master rebuild kit, so plan to replace them at the same time as the frictions, steels and seals, then refill with Dexron VI on the late units.

Does this set include a driver handle?

The listing describes 39 shouldered steel drivers. Most shops push them with an arbor press or tap them with a dead-blow hammer; check the package contents if you need a separate handle.

Will it do the 4L60E pump bushing?

Yes, the 4L60E is on the GM coverage list. Set the pump bushing to the factory depth; the GM procedure uses a position stop for that bushing, so measure before you start and after you finish.

Do I need this set or the 13-piece 700R4 set?

If you only rebuild 700R4, 4L60 and 4L60E units, the 13-piece set covers them. Buy the 39-piece set if you also work on TH350, TH400, Ford, Chrysler or older GM units.

Does it cover the Chrysler 518 overdrive section?

No. Chrysler 500 and 518 coverage is the main case only, not the overdrive housing.

Can the drivers remove old bushings too?

Yes. The same drivers push worn bushings out from the opposite side of the bore. Support the housing so you do not crack a casting.
