Bellhousing bolt pattern is different, Case is longer, and your trucks TCM won't work with it.
I have a Maggie waiting to go in to my '05, and I already shit the trans with just a program, exhaust and modified ignition.
I am on the fence to go with a PATC, Sharadon, or an ATS trans.
PATC guarantees 500hp, Sharadons Stage III is currently handling 750whp on thier 4x4 Rumblebee, and ATS says 1000hp with thier billet 3 clutch converter.
PATC is $2600 with a billet single clutch converter, Sharadon is $2900, and the ATS is $3500 with the 3 stage verter. However, the ATS trans is $1750, and the PATC Billet verter is $750 versus ATS verter for $1350.
I'm kind of leaning toward the ATS, with the PATC verter and sonnax line pressure booster.
Urggghhh. I know a few locals running the ATS stuff in thier diesels and love it. However the Sharadon guys are making BIG Power on 4wd Hemi's. PATC, well I kind of think they might be suppling the internals to Sharadon .
