When you as a driver wish to accelerate, the transmission shouldn't be your enemy. Now, before you say "You shouldn't have turned!", well, try hold that line of reasoning when you live in NYC, or Toronto, Miami, Houston, LA, etc, etc, or any area where traffic gets heavy during rush hour. You lean into the throttle to get moving, then hold the throttle as you turn, and then as you straighten out, you add more throttle to accelerate, but the trans has already upshifted and now won't downshift, regardless of throttle pedal setting, and there's a guy coming at you from behind honking his horn. Another example is when you make a right-hand turn onto an adjacent roadway from a dead stop. Not to mention that it startles the life out of Granny in the next lane over! No, this simply won't do.

Then more pedal, and as you run out of roadway near the merge and you're finally darned near full throttle, BAM!, the transmission drops down multiple gears and you move out like a scalded rabbit as if panicked. You dip down into the throttle and the vehicle accelerates s-l-o-w-l-y.You put down more accelerator pedal, and still slow progress. Picture this: You're in 4th gear at 45 mph and you see that you must merge ahead. One of the worst problems that exists with modern trans shift schedules are the downshifting characteristics. So, to begin our definition of what we expect from our vehicle, we'll look at the deficiencies of the current TCM programming and decide what we want changed.
By installing a new ERod engine and transmission and then adjusting the transmission shift strategy to suit your driving style and environment, you can achieve massive fuel economy savings compared to your old carbureted 350 V8 and 3-speed transmission while enjoying a far more satisfying drive. These are excellent goals to be certain, and goals we should only ever try to improve on by adjusting shift strategy based on our own particular driving environment.
The factory programs the Transmission Control Module (TCM) for the "average" driver as well as to make certain the vehicle performs as well as possible during the EPA fuel economy and emissions test cycle and to ensure long-term powertrain reliability. The key to tuning your 4L60E transmission properly is defining how you want the vehicle to behave under various driving conditions.

After all, if the transmission shifts the same way you would if you were driving a manual trans, we'll, that'd be awesome, and that's what we're going to show you how to do. Doing either option too often is a waste of time and money.Automatic transmission does exactly what you want it to do, you may end up loving it as well. “In a high-mileage car, power-flushing the transmission fluid can dislodge sludge and other particles, leading to clogs even after the clean fluid has been added.”Īgain, the best advice is to research your vehicle and know exactly when a transmission drain (or flush) is recommended. “There is also a distinction between simply draining and refilling a transmission vs. “If that’s the case, it’s likely a sign of a bigger and more complicated problem.” “This shouldn’t be a frequent occurrence, since a gearbox in good working order would not have metal shavings polluting the fluid over a short period of time,” Ibbotson says.
Getting rid of this dirty fluid makes sense, right? If it’s called for in the service manual, go ahead and let your mechanic do the job. Over time, the transmission’s interior components wear down, and tiny particles contaminate the fluid. Transmission fluid helps keep mechanical components cool and lubricated, whether the gearbox is automatic or manual. First, it’s helpful to understand the role transmission fluid plays in a car’s operation.
