Transmission Do's 
 
1. Back flush cooler to prevent contamination of new transmission and
converter.
2. If you intend to install a used converter, have it professionally flushed
and fully inspected before using it. Proper inspection includes measuring
pilot, hub, endplay and overall length and comparing those to the
manufacturers' specifications.
3. Verify that converter is property installed in transmission before
bolting unit into vehicle. Refer to enclosed instructions.
4. Thoroughly inspect your flexplate and drive shaft before installing
transmission. Look for bad teeth, cracks, loose or missing balance weights,
worn yoke or universal joints. These problems will cause vibration and other
damage.
5. ALWAYS install and adjust any required TV or kickdown cables exactly
according to the instructions. INADEQUATE PRESSURE WILL QUICKLY DESTROY YOUR
TRANSMISSION. Refer to enclosed instructions and/or vehicle service manual.
6. Verify shifter adjustment before starting engine. Vehicle should start in
PARK and NEUTRAL only!  Also, severe transmission damage will occur if unit
is operated between gears. Refer to shifter instructions or vehicle service
for procedures.
7. Check that the transmission cooler lines are not kinked or touching the
exhaust system.
8. If your transmission is equipped with a vacuum modulator it is VERY
IMPORTANT to verify amount of vacuum at the modulator with a gauge.
Automatic transmissions typically need a minimum of 12 in. Hg. at idle.
Throttle position increases should produce a quick decrease in the vacuum
reading at the modulator. Not enough vacuum will cause late, harsh shifts.
Slow response to throttle position changes due to a kinked or plugged line
will not property boost line pressure and will BURN UP YOUR TRANSMISSION.
9. Add at LEAST 4 quarts of transmission fluid to transmission before
starting engine to prevent damage. Continue filling with engine running to
proper level.
10. Re-torque the oil pan bolts after installation to 13 ft.-lbs. to prevent
leakage.
11. Run your transmission with the vehicle on jack stands so that any
mis-adjustments are corrected before they can cause damage.
12. Replace the TCIR installed filter after initial use. (Race - 20 passes;
Street - 500 miles) Bushings and clutches in an automatic have a break-in
that generates fiber and metallic particles. Click here for the part number
of the filter for your application.
 
Transmission Don'ts
1. Don't accept your transmission from the delivery driver until you
personally inspect it for cracks, dents or breakage. 
2. Never install a converter of unknown specifications or origin. IT COULD
BE THE WRONG APPLICATION OR, IF DAMAGED, IT COULD RUIN YOUR NEW
TRANSMISSION. 
3. Don't attempt to use a kinked metal or all rubber hose to connect your
vacuum modulator if applicable. Proper installation is a metal line
carefully bent, with just a few inches of rubber hose on either end for
connection. 
4. NEVER install a TV cable on a Holley carburetor without the proper
brackets. Your transmission WILL BURN UP as a result of inadequate operating
pressure. TCIR carries a bracket designed specifically for Holley carbs. 
5. Never use a solid transmission mount in any circumstance. This WILL cause
the case to crack because it is not designed to be a stressed member of the
chassis. 
6. Never install pipe plugs in the cooler fittings. A cooler loop, in the
very least, should be installed so that transmission lubrication is not
compromised. 
7. Don't use Teflon tape when installing cooler fittings into the case or
the case WILL crack. 
8. Don't overfill your transmission because this will foam and aerate the
fluid causing heat and low pressure problems. Be sure the dipstick and tube
are correct for your application. 
9. Don't use the vehicle if a problem is suspected with your new
transmission. Many times problems can be rectified while the transmission is
still in the vehicle, but, if the transmission suffers permanent damage it
will need to be removed. 
10. DO NOT hesitate to call TCIR at (662) 224-8972 or E-mail us if you have
any questions about your new TCIR transmission
