TRANSAXLE QUICK LEARN PROCEDURE
The quick learn procedure requires the use of the
DRB II scan tool and the 1993 DRB II scan tool car-
tridge.
This program allows the electronic transaxle sys-
tem to recelebrate itself to provide the best possible
transaxle operation. The quick learn procedure
should be performed if any of the following proce-
dures are performed:
• Transaxle Assembly Replacement
• Transmission Control Module Replacement
• Solenoid Pack Replacement
• Clutch Plate and/or Seal Replacement
• Valve Body Replacement or Recondition
(1) Plug the DRB II scan tool into the blue CCD
Buss connector. The connector is located under the
instrument panel on the drivers side of the vehicle.
(2) Insert the 1993 DRB II scan tool cartridge into
the DRB II scan tool.
(3) The red and green lights on the DRB II scan
tool will light up and then begin flashing. Wait until
the lights stop flashing before continuing with this
procedure.
(4) Press the number 4 key on the DRB II scan
tool key pad. Item number 4 will not appear on the
DRB II screen unless you scroll down. It is not nec-
essary to scroll down to be able to choose item 4.
(5) Press the number 2 on the DRB II scan tool
key pad (Transmission).
(6) Press the number 1 on the DRB II scan tool
key pad. Wait for the DRB II scan tool to perform the
following three tests before continuing (These tests
are done automatically by the DRB II scan tool).
• Buss Test
• Initialize
• Controller Part Number
(7) Press the number 5 on the DRB II scan tool
key pad (Adjustments).
(8) Press the number 3 on the DRB II scan tool
key pad (Quick Learn). Then follow the instructions
on the DRB II scan tool screen.
TRANSAXLE DISASSEMBLE/REASSEMBLE
Before disassembling transaxle, move the shift le-
ver clockwise as far as it will go. This should be one
position past the ''L'' position. Then remove the shift
lever.
Tag all clutch pack assemblies, as they are re-
moved, for reassembly identification.
CAUTION: Do not intermix clutch discs or plates as
the unit might then fail.
Measuring input shaft end play before disassembly
will usually indicate when a #4 thrust plate change
is required, (except when major parts are replaced).
The number 4 thrust plate is located behind the
overdrive clutch hub. Attach a dial indicator to tran-
saxle bell housing with its plunger seated against
end of input shaft (Fig. 1). Move input shaft in and
out to obtain end play reading. End play specifica-
tions are .13 to .64 mm (.005 to .025 inch). Record in-
dicator reading for reference when reassembling the
transaxle.
