Step 1 Before you begin - let vehicle cool for about an hour. Disconnect battery. Raise vehicle and support on jack stands. The higher you raise it, the easier it is to work under. If your installing a new transmission and converter, skip toSTEP 3
Step 2 Drain oil from transmission by removing the drain plug. This is a good time to install a TCI® Drain Plug Kit, TCI® #805800. Pans without plug must be slowly removed by freeing one end and allowing bolts on other end to hold pan. The pan will drop down to allow the fluid to run out the end. Use a drain pan to catch fluid. Remove remainder of bolts and slowly lower pan and pour remainder of fluid in drain pan. Replace filter and clean pan and install new pan gasket. (New gaskets and filters available from TCI®). Reinstall pan and torque pan bolts to OEM specs.
Step 3 Expose converter-flywheel bolts by removing converter dust cover.Ford and Chrysler- rotate converter to locate drain plug at 6 o'clock. Remove plug and drain converter. Separate converter from flywheel. Remove four (4) bolts on Chrysler, three (3) bolts on GM, and remove four (4) nuts on Ford. (You should get a box to keep all bolts, parts, and etc...so they won't get lost.)
Step 4 Remove driveshaft, disconnect speedometer, selector, and throttle linkage, wires, vacuum lines, cooler connections and remove dipstick and tube. Remove starter from bellhousing on Chrysler and Ford.
Step 5 Support bottom of transmission with a wide block of wood or use a transmission jack. Remove crossmember. Lower transmission slightly. Support rear end of engine if engine is mounted at front end. Remove transmission to engine bolts. Before separating transmission from engine, take precaution to keep converter in transmission - DO NOT ALLOW IT TO FALL OUT!! Remove transmission with converter.
Step 6 Remove converter from transmissioncarefully.
FORD C-4 & C-6 TRANSMISSIONS CAUTION!
Input shaft may pull out with converter. Be careful to avoid this to happen. Some Ford input shafts must be installed one way due to different length splines. Installing wrong way will damage converter. If shaft has slipped part way out, simply push it back as far as it will go. Inspect input shaft for wear and burrs. You may need to replace the input shaft. TCI® has several different applications available that can be purchased from your TCI® Dealer or factory direct.
(If installing new transmission, skip to step 3)
Step 1 Inspect the old converter hub for wear, scoring, or damage. Such defects indicate that the bushing that supports the hub should be replaced before installing the new converter. The front pump seal should also be replaced. Both of these operations should be done by a reliable transmission service shop having the equipment and experience necessary. The lip of the seal is delicate and the coil spring inside can be damaged easily. The body of the seal can be distorted by improper installation. The seal must also be positioned to its wiping axis.Failure to attend to these two steps can result in damage to the new converter and cause leaks.
Step 2 Inspect splined couplings (input shaft and stator support) for burrs and damage.A burred or damaged spline can cause installation to be difficult if not impossible.A burred spline can easily be corrected. Using a small triangle file, as shown inFigure1, remove all burrs the full length of the spline. After all burrs have been removed, position a straight edge in the same manner as the triangle file. Using the straightedge as a guide, check to make sure the splines are not twisted. Twisted splined shafts should be replaced.
