Switching servos

I currently have an S Servo in my c6. The trans had a b and m shift kit and a 3500 stall converter. I’m going to rebuild the trans here soon do to some slipping in 3rd gear. The shifts are firm and it all seems to work fine except when I’m cruising I notice I have to keep giving it throttle to keep goin when it’s warmed up. My question is should I change to an R Servo is it worth it and what else needs to be changed to accommodate an R servo.

If you were happy with the shift firmness before then not a lot to be gained. The S has a fairly small apply. There are other factory servo like a D or L or P that work well with bit bigger apply.
Yes the R is even bigger again.
Not quite sure what you mean have to keep giving it throttle, is that really a trans issue?

When cruising down the highway it feels like I loose momentum. My rpms don’t change so I give it throttle and I speed up but it feels like the transmission is slipping. If I lay into it hard I can feel something isn’t right, it doesn’t go like it should it will make a pulsing vibration if that makes any sense. It has a 460 with a turbo so when it spools up I have engine power but doesn’t seem to be getting to the wheels.

I bought the truck as is but I looked at the converter through the dust cover and it looks like a standard converter shell not painted like an aftermarket one might be. Is there a way to check if it was built? And the oil in the trans has some fine metallic flakes I noticed on the dipstick

I had an issue with my C6 that was just not right at upshift points and had a pulsating feeling while driving steady, I found this carnage that happened to the VB separator plate @ the converter check ball/valve orifice. I mistakenly installed the check ball instead of the valve, the results from that mistake are shown below. The early C6 VB's used the check ball, the later ones replaced the CB with the check valve, probably due to more contact surface area from the valve.






Hope this helps.
