Corvette servo install

[Egan]

Step 4: Pull the servo assembly out. There is a spring on the back side that will likely fall out:



That spring was resting on the protrusion seen here. Make sure you put it back on before sliding the new servo back in:

Step 5: Remove the clip, washer, and spring from the 2nd apply piston. Simply push down on the washer and spring and pop the clip out:





Then simply slide the shaft out:

Step 6: Disassemble the 2nd apply piston assembly. Start by compressing the cover (I used a c-clamp):



Once compressed, remove the circlip and uncompress the cover:



Take the spring out of the existing servo housing and move it over to the new one:

Step 7: Reassemble the servo. Start by compressing the housing cover again and reinstalling the existing circlip.



Unfortunately, I was only born with 2 hands, so I had to get some help:



Next reinstall the shaft:



And then slide the new housing over the piston. Make sure the seal is lubricated and fully seated:



Next install the new red seal on the piston and reinstall the spring, washer, and clip to hold it all together:

Step 8: Reinsert the servo assembly into the transmission – make sure that spring that fell out in the beginning is in:



Step 9: : Reinstall the 4th apply piston:



Install the new blue seal on the cover and push the cover in place. Again compress the cover and reinstall the original clip. I need an extra hand to do this. I also had to reseat the assembly a couple of times to get it to fully seat.



Don’t forget to reinstall the heat shield after you check for leaks and proper operation.

First impressions are a much longer, smoother shift between 1 and 2. I'll reassess after the 12 mile drive to work tomorrow.
