Draws the tailshaft bushing out of a Ford 5R55E extension housing on a screw pull, so nothing gets driven into the case or scored.
A rear transmission seal that starts dripping again a few hundred miles after you replaced it is almost always a bushing problem, not a seal problem. On a two-wheel-drive Ford Ranger or Mazda B-Series with the 5R55E, 4R44E or older A4LD, the fix is a new extension housing bushing, and the OTC 6913 is the puller made to get the old one out without damaging the housing. OTC describes it as similar to Ford special tool 308-070, so it does the same job the factory service procedure calls for.
The extension housing bushing supports the driveshaft slip yoke at the back of the transmission. As it wears, the yoke can move up and down, and that movement chews up the lip of the rear seal. The 6913 slides in through the bushing from the rear of the housing. Its pulling teeth catch the back edge of the bushing, and when you tighten the drive screw against the housing face it draws the bushing straight out. OTC lists the tool at 1.12 inch ID with a 1.37 inch OD across the pulling teeth. Because the load comes from a screw instead of a slide hammer or a chisel, the aluminum bore stays round and the seal bore behind it is not nicked, which matters because a scored bore will leak no matter what seal goes in.
Make sure the leak is really at the rear seal. Clean the area and check the speed sensor O-ring, pan gasket and cooler lines above it, since fluid runs back and collects at the lowest point. Our 5R55 fluid leak guide walks through the usual spots. Then pull the driveshaft and inspect the yoke surface. If the yoke is scored or the bushing has visible wear or a gap on one side, replace the bushing and seal together. A badly grooved yoke should be replaced too, or it will cut the new seal.
OTC lists applications for Ford Ranger transmissions, the 4R44E and 5R44E, 5R55E, A4LD, C3, T5OD manual, and the 6F35 and 6F15. The bushing removal applies to units with a rear extension housing, which means two-wheel-drive trucks. Four-wheel-drive versions bolt a transfer case to the back of the transmission instead, so check your setup first. This tool is not for the larger 5R55W and 5R55S housings used in 2002-up Explorers, Mustangs and the Lincoln LS. Parts for the whole family are on the 5R55 parts page.
If the truck also has a shift or pressure complaint, it is worth handling while it is on the lift. The 5R55 harsh or delayed shifts guide covers the diagnosis, and parts like the 5R55E Ranger shift solenoid kit or the 5R55E overhaul kit are the common next steps.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.

OTC lists it as similar to Ford special service tool 308-070, the extension housing bushing remover used in the factory procedure.
OTC lists Ford Ranger transmissions, including the 4R44E, 5R44E, 5R55E, A4LD, C3, T5OD manual, 6F35 and 6F15.
No. The tool works from the rear of the housing with the driveshaft and rear seal removed, so the housing can stay on the transmission.
No. It is a remover. Use a correctly sized bushing driver to install the new bushing square in the bore.
Four-wheel-drive trucks have a transfer case bolted where the extension housing would be, so they do not use this tailshaft bushing. The tool is for two-wheel-drive extension housings.
