Emergency help... Transmission

[RST Dana]

it allows finer control over which gear is used also if your towing you should be using the Highest Octane fuel available 91 or 93 octane

this will keep it from down shifting prematurely..

I don't care what the manual says about 87 the minimum octane.. it's pretty oblivious that 91/93 octane helps the engine perform better under load and under AFM...


STOPS Active fuel management engine knock (Verified by OBD2 computer readings )

(not talking about Valve clapping that is a whole another issue caused by AFM Rapid cycling loop while using low octane fuel 87)...

the highest speed i had AFM was 1900RPM 80MPH i think the Maximum Cap for AFM is 2,000rpm


Im not really interested in paying 10$ a gallon for 100 octane unleaded racing fuel just to bring the octane to 93 i would have to spend $60


if your interested in knowing my engine does not burn oil I check the levels of my fluids every 500 miles (oil changes at 4,000 miles )... it has 90,6xx miles on it..

I used 1qt 0w30 mobil1 and 5qt of 5w30 mobil1 Full synthetic EP

I believe M mode only limits the top gear the trans can shift up to. M9 does prevent AFM as others have said. Also, it won’t keep it from downshifting, or you could be stuck in 5th gear at a traffic light.

Some of those transmission upgrades you can do without removing it to extend its life behind the 6.2. See @skpyle thread with lots of photos on the subject.

It's cheaper to keep her.
