Thanks for your advice Greg!Here's what I do . If the valvebody runs modulated line pressure , use steel rings .
If a constant full line pressure use the teflons .
Believe it or not the teflons do seal very well and are required with the constant line pressure , in that situation the steel rings wear pretty quick
Modulated pressure is controlled to a point by the vacuum supply to the modulator . High vacuum = low load so pressure is lower. As the load increases when accelerating, the vacuum drops then you get a line pressure rise . With the 40-2 kit with a yellow spring from memory pressure will be around 100-120 at light load and as vacuum drops will rise to around 150psi, the green spring gives near 200
In comparison , constant line pressure as in manual valvebodies will stay up around 180-200psi continually.
Go with the steel rings you will be fine.
Does that 500HP kit come with an information booklet like the C6 kit does ??
Thanks Greg!Will be good with the steel rings with that 40-2 kit .
I agree the C6 info with the kit is very good . Would thought the C4 kit would have similar . Oh well never mind. If you're not sure of anything just shout , will help where I can .
Now to find the early type thinner teflons here . Rang my supplier the other day as they only list the later kits. Maybe i'll end up machining the extra from the ring grooves to use the kit I have
Got to go there this week coming and go through their box of assorted broken kits and fingers crossed find what i need
Great!They will be fine . Some are like that . Just checked a kit for one i'm doing now and they are chamfered a little . As long as they are snug in the grooves and fit in the bore they will run in nicely you'll be sweet.
I test every ring in the bore they will run. I had a kit a while ago that had one odd ring in it
I like to keep endfloat at the lower end of specs . 0.5mm or .020" is ok . I like to stay below that , on average .010"-.015".
You select the small #2 washer to set endfloat, then on the bech you must then select a #1 that is a snug fit . There is no relationship in matching them up. I did do a write up on here ages ago on teh correct way to set up.
Great info Greg! You are an goldmine!Oh no, definitely not the same . They must be selected individually. Basically the small #2 washer sets the endfloat in the trans , then you follow the procedure to establish the correct #1 washer for the pump so as to keep the high drum snug.
I have redone the write up i did previous and put the pics back. Have a read , hopefully helps or I can talk you through it .
