BW4447
This category holds six remanufactured BW4447 transfer cases for RAM trucks, under Transfer Cases. All six are manual shift units. They separate on three things: input spline count, whether the rear output is a bolt on yoke or a slip yoke, and whether the case has an electrical connection coming out of the rear case half. Get all three right before you order.
What fits what
Coverage is 2012-2018. Two units are listed for 2012-2013: a 2500 and 3500 with a rear slip yoke, vendor SKU RTC4447D-1, and a 3500 Cab Chassis with a rear bolt yoke, vendor SKU RTC4447D-2. Both of those are listed as not having an electrical connection out of the rear case half. The 2013-2018 units are split by whether the truck has the AISIN transmission. With the AISIN transmission there are two 3500 Cab Chassis listings, RTC4447D-6 and RTC4447D-3. Without it there is a 3500 Cab Chassis, RTC4447D-5, and a 2500 and 3500 with a rear slip yoke, RTC4447D-4. All four of the 2013-2018 units are listed as having an electrical connection coming out of the rear case half.
How to identify yours
Input spline count tracks the transmission in this data. Both AISIN listings, RTC4447D-6 and RTC4447D-3, are 28 spline input. The other four are 29 spline input. Then match the tag number stamped on your case. RTC4447D-1 carries tag 68069703AA with Hollander number 412-776. RTC4447D-4 carries tags 5146621AA through 5146621AF, also Hollander number 412-776. RTC4447D-2 carries tags 68069707AA through 68069707AD, Hollander number 412-781. RTC4447D-5 carries tags 5146623AB through 5146623AG, Hollander number 412-815. RTC4447D-6 carries tags 5146622AB through 5146622AH, Hollander number 412-793. RTC4447D-3 carries tags 5146624AA through 5146624AF plus 68322284, Hollander number 412-816. One note on the source data: the RTC4447D-6 listing is titled as a rear bolt yoke unit but its own application notes describe a slip yoke style rear output yoke. Call us before ordering that one.
Core charge and warranty
These are remanufactured exchange units, so a refundable core charge may apply. No core amount is published, so ask when you order. A 6-month limited warranty is standard. A 7-year / 1,000,000-mile extended warranty and a core fee waiver are available on request for qualifying remanufactured units, must be arranged at the time of purchase, and are not automatic. See the transfer case remanufacturing process and the warranty page, or call 216-250-6666 or email sales@varietyengines.com with your tag number.
