Aisin has a US manufacturing plant for its high volume transmissions. Thus why the manual is from Japan
3.6L was built in the US, but they moved production to Mexico for the 2nd gen
Ecodiesel gets the ZF-built 8HP75. Itās a different transmission
A lower numerical ratio means a physically bigger gear to handle the torque input.
I donāt know the D478ās dimensions but I imagine they are very similar to NSG370, which was 25ā long vs 32ā for the TR-6060
Thatās incorrect.
1994 YJ also used a 3-speed automatic transmission (30RH/32RH)
Wrangler did not get a 4-speed automatic until the 2003 model year
Maybe you are thinking of XJ or ZJ
Mineās a 1500, the HDās use a different beefed up version (8HP75āLCV).
eTorque is only 49 lb-ft and doesnāt add to peak torque. So it would make no sense to change transmissions for that.
Ironically, Dodge still uses the smaller 8HP70 in the 6.4L Durango even with its 470 lb-ft torque
TJ got entirely different seats for its ārefreshā... new cushions, new frame (1ā lower), redesigned contour and completely different fabric... thatās not āa color changeā
Same as JKās seats were changed in ā13
Chrysler uses blueprints but not exact ZF design, they are allowed to make changes under the license agreement.
ZF makes the 8HP70/8HP75 in both the U.S. (SC) and Germany
Yes, my 8HP75 runs significantly cooler than the 195-199F my previous 8HP70 used to sit at while towing 7-8k lbs
