In short, an automatic transmission shift kit modifies the transmission’s shift timing in order to dramatically increase shift firmness and durability of the transmission components. … Transmission shift kits can reduce this overlap time while improving the overall shifting action.
Is a shift kit hard on a transmission?
Why do they make the transmission shift harder? Shift kits simply eliminate many of the restrictive oil flow problems in the transmission’s valve body. The results are firmer shifts and reduced slippage and shift overlap.
Can you put a shift kit on an automatic?
A shift kit is a set of components for automobiles designed to improve how well the car shifts between gears. Kits are made for both automatic and manual transmissions.
Should I install a shift kit?
Installing a shift kit can also help your transmission last longer. This happens by reducing the slippage and shift overlap that is inherently built into a transmission to create those smooth shifts. … In short, the valve body is like the nerve center of the automatic transmission.
Is shifting gears in an automatic bad?
Or vice versa? If so, you need to stop that bad habit immediately. Shifting too quickly while your car is still in motion can cause significant damage in the transmission because there is a spinning coupling mechanism that can prematurely fail if it becomes worn from the harsh gear change.
What does a TH350 shift kit do?
At least half a dozen shift kits are on the market for the TH350 transmission. They all share similar components and are designed to improve shift performance by increasing line pressure, volume of fluid to the clutch packs, and timing of the shifts for less overlap and shorter/ firmer shifts.
How much does a shift kit cost?
The cost of an automatic transmission shift kit can range anywhere between $50 and $970.
What are the symptoms of a bad valve body?
The valves will wear down, the channels can be abraded and become oversized, and the whole valve body unit can become warped. Signs of a bad valve body can be fluid leaks, slipping during gear changes, or even failure to go into gear.
What does a 4l60e shift kit do?
Several companies offer shift kits for the 4L60 transmissions; however, installing a shift kit can be a detailed and complicated process. Shift kits are designed to reprogram the shifting of the transmission. They do so by controlling the flow rate, pressure, and timing to the various components of the transmission.
What does a valve body upgrade do?
The Valve Body Upgrade re-calibrates the hydraulic valve body to provide shorter duration shifts while under load. This is achieved by increased pressure and volume to enable the clutch packs to apply quicker with greater clamping force.
Can I reuse valve body gasket?
That gasket is pretty durable. You shouldn’t have a problem reusing it just as long as it doesn’t get kinked, and develop creases.
What should you not do in an automatic transmission?
Auto Advisory: 4 things you should never do in an automatic transmission vehicle
- Never coast down a hill while in neutral. …
- Stop the vehicle completely before changing the gear. …
- Don’t launch your vehicle. …
- Never put your car in neutral at a signal.
