1. Sequence of Removing Blue Label Transmission.

The steps A-J are straight forward.

2. Removal of Pilot Bearing.
A 9PC Blind Hole Slide Hammer Pilot Bearing Puller Internal Extractor Removal Kit was used to remove the pilot bearing.


3. Installation of New U-Joints in Main Drive Shaft.
Dana Spicer 5-3613X U-Joints w/Coated Caps for Alum Driveshaft were installed on both ends of the main drive shaft.


4. Intallation of Rebuilt Black Label Transmission.
ZFdoc Rebuilt 91' Black Label ZF S6-40 Transmission was lifted into place using a Harbor Freight 800 lb Capacity Transmisison Jack.


Transmission Jack
The Transmission Jack works perfectly with the ZR1 on KwikLift 18 inches off the ground (Perfect height). The 800 lb Capacity Transmission Jack has roll and tilt adjustments for a perfect match when locating the transmission on the Bell Housing (Clutch depressed last 2 inches of installation). The transmission (on Transmission Jack) can be rolled under KwiKLift from the front as the shifter will clear the cross members and bell housing/oil pan (slipped along side of oil pan).

Rebuilt Black Label Transmission Installed

5. Test Drive

Went for a test drive with several stops at 25 mph wearing off the Black Powder Coating from the Wilwood Rotors. Then some high speed stops and even some speed shifting. WOW....that ZFdoc Black Label shifts so crisp and easy it is amazing when compared to Stock ZF S6-40 Transmissions. ZFdoc Rebuilds are recommended for anyone having Transmission issues and for those that want the best shifting Transmission available for the ZR-1.

And if you want to STOP QUICK.......Wilwood Rotors with C5-Z06 conversions are the way to go
