I thought the idea behind this post was to establish if 04 trans can be used in a 97-98 Lincoln Mark VIII without changing the output shaft. I'm sure I'm not the only one who would appreciate any info on this.
I don't know about 500rwhp guys, but I do know about over 100 trilogy marauders in the neighbourhood of 450rwhp that still use original 03-04 transmissions. Mileage varying from 1k miles to 50k miles.
Yeah, I forgot about the output shaft. Sorry about that. The 4R75W output shaft doesn't have speedo gear teeth on it.
Also as I alluded to above, there is an issue with the OSS that will need to be addressed in the tune by someone with the software and knowledge to fix it.
You guys know that the differences between the 4R70W and a 4R75W are minimal with the major changes being a redesigned intermediate piston assembly and the addition of a turbine speed sensor to monitor slippage of the forward clutch on the 4R75W. These transmissions both have the same amount of clutches in each clutch. And actualy I think that the reverse sun shell is weaker on the 4R75W due to it being a riveted design. There are other changes, but it isn't like they redesigned the whole transmission and beefed it up a lot. It is still mostly the same transmission.
