Paramount 545RFE built tranny

[2010 Infantry Vet]

been looking to either add a magnacharger (with forged 5.7 internals) or swap in a car 6.4L motor, and have been looking at tranny options. From what I have gathered, Bill at Paramount has assured me their upgraded 545 will hold up to the punishment. Just thought I would share.

Damn that is starting to get into the serious upgrade status!

6k on a tranny
6k on a supercharger
1500- 2k on forged internals

What do they mean when they say upgraded valve body ?

That’s why I haven’t spent any money on bolt ons. Do the tranny first, then motor, then blower. Ain’t cheap to go fast!

My trans has been trying to die for over a year now but I keep nursing it along. Now I know who to call when it kicks the bucket on me.

You have the same end goal that I do. Forged internals with a blower lol

I am curiousto see how the Paramount unit works out. Nobody else has been able to truly make the 545/65RFE last, so I'm hoping they finally have something going here.

Having said that, you can still make big power in a 5/6sp truck on the stock transmission. I had heads, cam, every bolt on you could buy, and nitrous on my 2011 Ram that still had a stock transmission that ran perfect at 83,000 miles. Knowing how to drive the truck to prolong the life of the transmission has been more important than the components in the transmission on the 5/6sp.

Dont do any wide open throttle downshifts out of overdrive, and you are good.

I also own a Grand Cherokee SRT and a lot of the SRT owners who are upgrading the motors (supercharger or turbocharger) go with the Paramount trannys. They have a good reputation with the SRT community.

Jesus Christ you could put in a Lenco at that buy in and really scare your friends

I ran a 65rfe built from Paramount for 3 years before pulling it out for a refresh and in the process of finding time to do a 4l80e swap.

I asked for the specifics of what they do to beef it up, and he wouldn’t say, and I don’t blame him. Then everyone will copy him. Just like how guys that run good dyno numbers with custom cams won’t tell ya the specs.
I spoke with the owner of paramount, and he said he still has the same tranny in his own truck, and is running over 600 rwhp with no issues.
Yeah you can try to prolong the factory tranny, but I’m not the kind of guy that likes to be able to depend on my stuff.

For the price of bolt ons, you could have a blower. Hence why I’m not buying any bolt ons. Wait till it blows, then build a forged motor.

Are the internals on the srt engine beefed up ?
