What does a shift kit do 700R4?
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.
What does a 700R4 servo do?
Arguably one of the most inexpensive, yet most rewarding upgrades to your 700R4 or 4L60E (4L65E, 4L70E) transmission is the corvette servo. The corvette servo will give your transmission 50% more apply pressure, which is just what you need to keep from burning your transmission up under heavy load situations.
How do I upgrade my 700R4?

- Take Off the Pan and Filter.
- Remove the 1-2 Accumulator.
- Remove the Auxiliary Valve Body.
- Unbolt and Remove the Throttle Pressure Mechanism.
- Remove the Valve Body Bolts.
- Remove the Pressure Regulator.
- Choose Spring Type.
- Insert a New Separator Plate and Gasket.
Is a 700R4 good for racing?
Racing with a stock 700R4 while in overdrive risks the integrity of the O/D band and limits your performance in a drag race, and can ruin the transmission. But a custom built 700R4 is made of sterner stuff, and reduces the lag time introduced by sloppy and sluggish shifts.
Does a shift kit improve performance?
There are different types of shift kits designed for different tasks, but generally speaking, a performance-oriented shift kit is designed to provide firmer shifts by changing the flow of transmission fluid through the valve body. By “firming up” each shift, a performance gain is actually achieved.
Is a shift kit good for a transmission?
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.
What does a super servo do?
This billet aluminum Super Servo is the 4th Gear apply piston & outer cover. This upgrade gives you better holding capacity in 4th gear. Firmer 3-4 shifts and more positive 4-3 down shifts. Installing this servo in lower mileage vehicles can add years to your transmission’s life.
Are 700R4 transmissions good?
The 700R4, produced by General Motors/Hydramatic, is considered one of the best overdrive transmissions ever made. This transmission was introduced in 1982 as a replacement for the TH350 transmission, with the primary goal of improving fuel economy .
Are all 700R4 transmissions the same?
All 700r4, 4L60, and 4L60E transmissions have the same gear ratios. The major differences are external. Electrical hookups, speed sensor hookups, calibration, and converter stall are the main differences. All of the traditional bellhousing applications (sbc, 4.3,…
Is the 700R4 transmission an automatic?
The 700R4 transmission is an automatic transmission that was found in GMC and Chevrolet cars and trucks. It was developed with the aim of improving fuel economy in cars, and it achieved this goal thanks to the overdrive it featured. Over the years, the transmission has had a change of name, and there have been significant upgrades to its build.
How many bolts does a 700R4 transmission pan have?
The 700R4 transmission is made from cast aluminium, which adds to its sturdiness and ruggedness. It’s 23.4 inches long, weighs 155 pounds, and has 16 bolts. The tail shaft housing is connected to the main case by four bolts, and the bolt spacing is comparable to that of the THM350 transmission.
