Transmission Installation Procedures
The following must be checked and replaced, if needed on all automatic and standard transmissions where applicable
· CONVERTER INSTALLATION:- Make sure the converter is all the way into pump gear-don't assume its in place when you receive the transmission. After you are sure it is in place, always keep tail end of transmission low so it cannot slip out. This is the #1 cause of failure at time of installation, or soon thereafter. Complete Instructions
- CONVERTER WHEN NOT REPLACED:- Must be removed and thoroughly flushed. Make the following inspections: thrust washers for misalignment, condition of inner sprag, hub condition for wear and mounting devices to insure proper alignment.
- COOLER AND COOLER LINES: - Must be flushed to remove all metal particles and oil. Don't just blow out with air. Use a solvent that will flush out old oil and metal particles. Install a Protection Kit!
- FLEX PLATE: - Inspect for cracks where plate bolts to engine and out of round holes where converter bolts to flex plate.
- MANUAL CONTROL LINKAGE: - Must be re-adjusted to assure proper settings for unit being installed. Adjust linkage with car in actual road operation.
- MOTOR AND TRANSMISSION MOUNTS: - Their condition will affect linkage adjustment and cause excessive wear to internal transmission parts if worn. Also, broken or oil-soaked mounts must be replaced.
- U-JOINTS AND DRIVE SHAFT YOKE: - Rough and worn u-joints may cause vibration in drive line and failure of bushings and seal in tail casting. Rough or worn (tapered) front yoke will quickly damage rear seal and bushing, causing loss of lubricant which can lead to transmission failure.
- ENGINE: - Many transmissions depend on engine vacuum for proper shift pattern. Good engine performance is a must to insure proper vacuum. If engine vacuum is too low it may cause the transmission to have a short life.
- DO NOT: - Check out transmissions operation with the drive wheels off the ground.
- DO NOT: - Re-use old oil. Dirty oil causes valves to stick and may clog lines if contaminated, both may lead to premature failure.
- SHIFTER PLATE AND SHIFTER FINGERS: - Because of the various styles of shifter controls it is impossible to always supply the transmission with the proper shifter plate. It is of great importance if the shift fingers indicate any wear they must be changed. Worn fingers may cause too much gear movement resulting in noisy gears or improper synchronizer application. Shift arms must be the exact kind as on the original transmission.
- SHIFTER LINKAGE: - Excessive wear of shifter linkage in shifter tube (in steering column) may cause malfunction in shifting. Too much wear at these points may cause improper throw or movement of the desired gear at the proper time. Sloppy shifter at steering column, dragging effect, in or out of gears or jumping out of gear all indicate possible linkage trouble.
- CLUTCH UNIT AND PILOT BEARING: - The clutch must completely disengage to properly engage first or reveres gear. The condition of the pilot bushing will determine how well the transmissions front shaft is supported and how freely the clutch disc will operate.
DO NOT ASSUME THE ABOVE ITEMS ARE GOOD. CHECK EACH ONE THOROUGHLY.
THE OPERATION AND DURATION OF SERVICE OF A TRANSMISSION DEPEND ON THE
ABILITY AND EFFORT OF THE INSTALLING MECHANIC.
THE DRIVER OF THE VEHICLE IS RESPONSIBLE FOR MAINTAINING PROPER FLUID LEVELS
AND PREVENTING THE TRANSMISSION FROM OVERHEATING. OVERHEATING CAN BE CAUSED BY
SEVERAL THINGS SUCH AS RADIATOR CONDITION, PULLING A TRAILER, SPINNING REAR
WHEELS WHEN STUCK, RUNNING LOW ON TRANSMISSION FLUID, ETC...
