545rfe ?s

I did Email another company several times Modern Muscle Performance about a harness and a ECU using my trans and controller but they never bothered to get back to me.View attachment 1715069937

I sent a message to David at Modern Muscle to ask about getting installation instructions (if there were any) that comes with his kits for the Hemi swap because I had two shops work on my 6.1 hemi/545rfe swap into my Duster. I was having some issues and if there were some install instructions I could use that to go back over what was done to make sure stuff was correct... Never got a response. So had to take a lot of time to figure stuff out by going over everything.

In all honesty, unless the engine is stock I would stay away from the 545 or have it built to handle more. Several guys have put 6.1's in front of them only to kill the trans pretty quick. So if at any point you want to go to a performance build you may want to investigate this.

I the 545 is not so good, what would you reccomend?

With my swap I have about 800 miles on my 6.1/545RFE/8.25 rear with 2.73 gears. Going along with kb67mopar was stating... If you are going to look to be hard on the car, hard acceleration, do burnouts, and what not yeah you most likely will kill the 545RFE. Yet it would seem if you are looking to do more casual driving/cruising, That tranny will do you just fine as it has for me. I love the five speeds and overdrive. I cruise at 60 mph at about 1500 rpm and my Duster is a great hwy car.
