If they are worthwhile for low-mods cars do you have a
"everything that goes in that hole, do it once" kit?

What I would do to confirm this is look at the trans data when it's tagging the RL or just before. If the computer is telling the trans to shift and it is not it could be a few things. Sticky valves,flooded solenoid,burnt 3-4 clutch,cross leaks,etc. What is the condition of the oil? The first to do is to look at to look at the trans data. Vince
i changed the entire valve body solenoids and all. the fluid is clean and doesn't smell burnt this condition has been present since first rebuild. i had a transgo hd2 installed, but was removed to see if the valve body had a sticking valve. where would i start looking for cross leaks? appreciate your help. is there a possibility the cross leaks are in my servo?
If you are referring to the sonnax servo's the answer has to be yes. The second servo has seals everywhere to seal up all possiable leaks. I really like it. The vette servo is great for all applications with the seals that we use. The sonnax has more holding power and also sealing power as I stated. I think it's great for the guy that wants the best he can have and is looking at a billtet style servo. I do think that they are fine for most all applications. We do stock them as "everything that goes into the hole kit."LOL The only thing that you might to do is adjust the pin length for proper band adjustment. Vince.

- 18% more apply area than OEM Corvette servo
- Dual seals on 2nd gear servo piston, separator piston and between
- O-ring seat between 2nd gear piston and servo pin
- Two seal rings between case and servo pin
- Servo piston and separator pistons are made from 6061-T6 aluminum
- Servo pine is made from Chrome-moly steel
- Kit includes all necessary seals
- Affects 4th gear only
- Can be used with OEM, Corvette or Sonnax performance 2nd gear servo assemblies
- Easy to install: Transmission removal is not required
This info is directly from sonnax. These servo's as a combo have been tested since 06/05 with great results thus far in our units. I hope this info answers your question. Vince

i just swapped to the jet servo for the 1-2 shift and i do feel a better grab compared to the sorry stock one ... they say its supposed to be better than the vette servo but yeah the sonnax servos goin in next with a shift kit prob transgo stage 2 or full manual
