4r75w?

Just got the latest issue of Road and Track in the mail the other day, happened to read the preview of the 2004 Marauder:

"A new heavy-duty 4R75W 4-speed automatic transmission... The new transmission, which features Teflon seals and needle bearings, uses an 11.25-in.-high stall speed torque converter. The result is quicker shifts as well as ability to kick down into 1st gear at higher speeds."

So what's the deal with the 4R75W? Viable transplant option into the MN-12?

Sounds like it could work!

On the other hand, I thought the Marauder was scrapped...

I just doubted they would make a transmission solely for the Marauder...

Anyone have info on this thing? What makes it different than a 4R70W?

I bet that tranny was made to put behind the 3V 5.4L in the new trucks and since they had it the Maurader got it too.

Former owner of 94 Bird with DOHC 4.6L swapped from a mark VIII

2011 CTS-V Wagon
1968 Torino was an original 289, C4, fully documented numbers matching car. Now: DOHC 4.6L/T-56 swapped, Cobra intake, IMRC delete, BBK long tubes and H pipe. Dynotech Aluminum Driveshaft, 9" rear with TrueTrac and 4.11's.

Sounds just like a SLIGHTLY modified 4R70W to me... A dennis trans or other trans built to "the man"s specs should be just as good if not stronger, unless there are other upgrades I'm not aware of. However, I wonder what the stall is on that 11.25" TC - higher than the mk8 TC? Maybe we'll have a new mod.

yeah , what is the stall, if the teflon pump rings and stall are the only updates than I think it would be cheaper and better to just buy a stall and rings www.performanceautomatic.com has teflon pump rings and there really not expensive. I dont know enough abou this tranny yet though I gues it also depends on what year your Mn12 is
