Went over to help Mark(bada44) get his ATS 545rfe trans in his truck. While I was there, he showed me the 8HP70 trans. It's a little smaller and lighter than the 545rfe trans. Thought the 8HP70 trans was bigger and weighed more... That's a nice surprise. (y)

it's 30-ish pounds lighter. and there are no clearance issues anywhere, which is very nice.

First thing - Amazing thread. I am looking to do this soon as I just had a new VB put in my 4yr old 545. Here is my truck as is:

2009 Ram 1500 SLT 4x4 Quad cab 6.5' bed | 8" Lift | 37's | 4.56 gears| 6.1L (5.7 based) | GR .5HL v2 Thump cam

I have a trans from a 2017 Ram 1500 8HP70 and am ordering the SGA kit with Shifter. I am going to stick with my 4.56's I think, just because of my big 37's (probably going to 38" or 40" soon)

What is needed?
1. 8HP70 Truck Flex Plate - 4752574AB
2. 8HP70 Pilot Bushing - 4736283AA
3. 8HP70 Cooler lines - 52014804AI (I can run these to my current trans cooler in the radiator correct? My 545 runs about 170-200 right now.
4. SGA says to modify my crossmember as needed. What is needing to be done here?
5. Front Driveshaft Spacer. Anyone have a link for this?
6. Front Engine Diff Mount "Cut 545 one and weld to 8hp70 one". Any pics of this from anyone? 8spd mount = 68149798AB
7. Do I need a new Started as well or will my truck one work since its a truck 8spd going in?

Also with the Gear indicator is there anyway to get the EVIC to show the gear by wiring into it instead of a gauge?

Let me know If I am missing anything. I am hoping that my truck being an 09 that it will be more straight forward. Also with the 8" lift it is easy to get under and get it done :)
