68 rfe trans line pressure booster question
 

ANYONE USING THE TRANSMISSION HARNESS ADAPTER TO BOOST LINE PRESSURE ON THERE 68RFE? PRO'S AND CON'S TO USING IT ON STOCK TRANNY?

Just spend your money on H&S Overdrive for a little more money. Or contact Suncoast for a transmission tune, or you can even look at ATS for quite a bit more.

Simply put, the programs do way more than the harness and are only a little more money.

Wondering the same thing. Already have a smarty jr. Is the pressure booster compatible with a smarty jr?

Bought one put it on truck for 3 days then started slamming gears up and down messed it all up. Reflashed tranny works fine again. Sitting in my tool box i think. Pay shipping and you can have it text me 5412977973. But imo its a pile of sh!t and will cause nothing but problems

Im running the sonnax on my 2010 and it felt alittle firmer but no shifting issues and its way cheaper then the bd
