Also the 545rfe tcm modulates the lockup engagement and disengagement to enhance the quality of the shift for a smoother transition.

So I have 179k on the trans. Will the tc put more strain? Or does do it gradually

Haha.... faster they go the more strain you'll have.... I'm not a fan of the 545rfe and have little good to say about them...

The 4.56 gears will help take some of the strain off the 545rfe trans. Normal driving with a 2800 tc is easier on the trans as well. But, with all of the miles on your trans, and the mods you have done to your Hemi engine. Your 545rfe trans will be the weak link. Would be a very good idea to replace your high mileage 545rfe trans. You have a few options. ATS completely rebuilt and updated 545rfe trans and Copilot would be a great performance option. Clint and his ATS team have put in many hours and modifications to the 545rfe trans to make it stronger and more reliable than it was. Swap to a 6 speed manual trans is a good fun option. But, any trans swap will cost you time and money to get it right...

PS. This is just my own opinion. Please take it as such...
I don't prefer the 46rh trans swap for a street truck. There's allot of mods that have to be done just to get it in there and working as it should. And, if you do your research on this site. You'll see that their having problems as well. But, for a drag race truck, different story. Once again, this is just my own opinion.

Lol I feel like the 545 is always the weak link. It's been an awesome truck for the past 11 years. I think that's a good run. I'm excited to see how she does with the high stall

Even with the mods and all I'm prolly just at 400 hp crank. I talked to procharger and even Keith said I could get away with 500hp on stock 545. I might just take the chance

If you can have someone add a Sonnex Smart Tech OD hub, Sonnex line pressure kit to a rebuilt 545rfe. "No shift kit needed." Add the accumulator plate kit too. You should be good to go.

Smart-Tech® Overdrive Clutch Housing Kit - 72960-06K - Sonnax

Line Pressure Booster Kit - RFE-LB1 - Sonnax

I looked at the line pressure booster but alot of what I read says the computer will manage it out in a month and it will stop increasing the line pressure. Is there truth to that? Also from what I was reading that if you have a custom tune then the lone booster doesnt help anyway. I know diablosport deleted trans tuning in the 3rd gen so it might be old information I was reading
