Sonnax Trans Line Booster?

Really looking into installing one of these, but i am wondering if there is any justification to think that increasing the line pressure with stock parts would cause them to wear down faster.. am i right in thinking this?

I know increasing the line pressure would reduce the chance of clutch or band slippage in high-torque situations, but would increasing the clamping force for daily-driving cause the bands or clutch or even the torque converter to experience faster wear? I assume there is a pressure regulator to control excessive pressure, but would a slightly increased line pressure cause stress to the mainline pump? Am i overthinking this? haha.

Haven't installed a rebuild kit yet, although i'd like to. But would it be smart to install a line pressure booster without the rebuild kit to fortify the mechanical parts? Sorry if this has been discussed elsewhere, but the search function doesn't seem to work for me since the forum redesign..

Thanks!

The Sonnax parts are well-designed and well-built. I used several when I rebuilt my transmission.

If they offer an integrated improvement / solution for your transmission then it should be strongly considered.

There are many upgrade parts I used when I rebuilt my transmission, all shown in the link.

My transmission has a high-volume cooling pan, upgraded servo pistons, better valve body parts, improved ratio holding band lever and actuator, better friction discs and more discs and steels per clutch.

What transmission is in your vehicle and what upgrade parts are available?

545RFE auto-five speed. Electronic convert clutch.

I think upgrades, besides major overhauls, are just the Sonnax line booster, a 45RFE Transgo reprogram kit, and spring upgrades.

The #8X cast aluminum pan might fit. It lists Dakota and RAM, but the same transmission.

If doing a rebuild, don't neglect the Torrington bearings.
