47RE "if it's not broken Don't - - ???"

My 47 RE Tranny is in great shape I don't abuse it, but I will be towing my boat & trailer this upcoming summer total towing weight 10K......Looking for common sense advice
on whether it's advised to upgrade it slightly with GM governor solenoid & BD pressure transducer......when I do my next fluid change I'll be adjusting the bans as well.
I'm just thinking about swapping out a few vulnerable parts in the 47RE to slightly improve it without building a new one and hope the old adage is wrong..."if it's not broken
then don't fix it"

I would recommend a Borg Warner HD solenoid and a Rostra HP transducer instead of the ones you listed.
Can you give me a reason for your choice instead of the GM & BD?..............Thanks
Dynamic........Would adding a full flow manual valve to complement the BW Solenoid be a good idea?........ Thinking it would allow for a cooler charge in park?
Also as you said, Very stalk difference in prices for The GM governor solenoid upgrade ($144) and the BD pressure transducer kit ($165) ........Borg Warner HD
solenoid ($41) and Rostra HP transducer ($45).................I just ordered the BW Solenoid and will order the Rostra transducer. ......Do I need a billet housing
for the BW Solenoid......maybe for better fluid flow??
Would you have a link for this manual valve?.....really appreciate it!.....recap: Borg Warner HD Solenoid, Rostra HP Transducer & Full flow manual valve ...best means for this DIY without removal......Thanks again for the $$ saving tips........Scippy
Thanks Storm appreciate it!
Dynamic.........I was able to purchase "separately" the Sonnax manual valve ($26.99) from Feiock Performance for my 47RE to go with the Rostra pressure transducer I purchased 2 days ago along with the Borg Warner pressure solenoid.
I also picked up a spare Accumulator spring.............Hopefully with these few additions I can say I've done the most before dropping the transmission ........Thanks Scippy
You can buy the Sonnax valve separately any time you want, but it doesn't work nearly as well as the Superior. But, it's better than nothing, I guess.

There's plenty more that you could do in there without pulling the transmission. It just depends upon your goals and your budget.
Would the "plenty more you can do" be too much for you to name ?.........just trying to absorb all!......Thanks, Scippy
Thanks Dynamic you certainly have broadened my knowledge of the 47RE ..........much appreciated!..........Scippy
