The 93 trans has different ratios. The 3.6 ECU and TCU might also not be
compatible with the 93 trans.
All V8 automatics have the same ratios in all gears and the final drive.
There is no difference electrically between the transmissions for any year
1990 ATU code: "Type 44" style axle flanges, early fluid line routing
1991 AYU code: "Type C4/B4" style axle flanges, early fluid line routing,
These transmissions are interchangable between 1990 and 1991 models by
simply swapping the axles flanges to match the axles.
1992- 1994 AGZ code: "type C4/B4" style axle flanges, late style fluid
routing with direct lubrication of thrust bearing, second fluid cooler added with
its own thermostatically controlled fan. Several internal mechanical
upgrades to increase durability. speedo trigger wheel matched to later style powered
Installing an AGZ into a 3.6 car requires:
Using 91-94 axles as the flanges are NOT interchangeable with the early
Retrofitting the entire cooling line and cooler setup to the earlier car or
fabricating custom lines.
Speedo sensor power wire connected (the wire is in the trans harness, its
just not connected to anything in the 3.6 cars)
An electronics mismatch dictates using the trans harness and TCU for
whichever engine is installed. ie: if installing an AGZ into a 90/91 you retain the
90/91's trans harness and TCU.
I've done the swaps and each is fully functional and doing daily driver
duty with the respective owners.
