be installed without removing the transmission or valve body. Cost $75.00
2. 700R4 Corvette intermediate servo.
This
is the servo that comes from the factory in Corvettes and high performance

This Super-Hold Servo has 40% more holding power (fluid apply area) than the
stock overdrive servo and gives a firm 3-4 shift. Can be installed without

3X.
700R4 high performance overdrive billet servo.
New on the market, this Maximum Overdrive Servo has 50% more holding power
than the stock overdrive servo. Talk about your extra firm 3-4 shift, this is
it. Good for towing in overdrive. Can be installed without removing the
transmission or valve body. Right picture. Cost $85.00
4.
700R4 Mega Valve.
The Mega Valve will increase your fluid pressure and firm up all your shifts.
This is the one you've heard about. Comes in two sizes .471" for firm
shifts and .500" for extra firm shifts. Can be installed without removing
the transmission or valve body. Cost $25.00
5. 700R4 high performance / high volume pump rotor kits.
Turn your seven or ten vane pump into a thirteen vane pump. This kit will eliminate irregular pump pressure above 5,000 RPM. Transmission must be removed to install this kit. Cost $45.00
6. 700R4, 29 element Borg Warner forward input sprag.
Fits late 1987 up, call on 1982 to early 1987. Upgrade your 700R4 to 1993 4L60E standards. This 29 element sprag is much better than the factory 29 element sprag because it has a double cage. Cost $45.00
