Servo comparisons?

[jakeshoe]

OK,
Just doing some comparison testing here.
A stock GN servo outside diameter is ?
A TH200 solid servo is 2.890, this is supposed to be close to the "Super Servo"
What are the measurements of the PTS servo?
What about the generic Super servo available from Superior or Sonnax or whoever makes it?

The PTS servo comes with the adjustable pin, inner sealing rings right?

Any other advantages?

Anybody bought a generic Super Servo, how's the quality? What all does it come with?

jake ,make sure you have the 200 servo w/the last numbers on the piston being 12 .this is the biggest one and there are 4 sizes.also the third accumulator side has more area than any one available giving a clean firm 2/3 shift w/out any bind at all .as a matter of fact ,itll bark the tires in 3rd w/out drilling the plate or skyjacking the line pressure ......................the real rotor and slide KILLER.(besides a crooked hub).there is no need for anything other than a 200 3speed servo in a 2004r as far as im concerned .we only put em if the customer requests it otherwise they will just collect dust on the shelf.an adjustment pin is a waste of time and money as the xtendo pins available for 12 bucks are a lot cheaper and furnish the same results.

The Sonnax Servo is a refined remake of the old 200 one piece servo. They fixed all the sealing issues the original 200 servo had IMO but stopped there. The largest one that I have seen and also does away with the downshift clunk that you get with other super servos. Has the most sq in fluid apply of all the servos. Not a generic servo at all. Has potential but still needs refinement for the money.

The superior servo is the original fairbanks servo the same servo that most of us have used for years. This servo can have pin problems and I have seen some tolerance issues on a few. Bruce has fixed that issue with his servo by adding seal the pin area and holding tight tolerance. The superior is a great servo but know what to look for.

The old 200 servo is a good servo shifts great no clunky down shifts but the sealing just plain sucks because of the teflon seals. In a pefect case when they seal properly they kick some butt. Pin adjustment is a pain. The travel is short and can be very hard to use on some direct drums that have been machined.

Those are my opinions on the ones I have used.

its easy to seal up.just use a 700r4 governor cover gasket on the big end and a toyota a340e servo seal on the small end ....presto no leaks.
