a friend dropped off a 1988 700-r4 and wanted me to tear into it and see what I could find wrong with it . I got it gutted and the most obvious thing is the spacer plate is trashed . Huge bulge from the concial 1-2 accumulator spring and the the check balls have done a number on the...

Any possibility the 1-2 accumulator housing with the sleeve and checkball is not compatible with the X plate ? Thanks . . . . Gordon

Need some opinions , comments , corrections , scoldings or whatever . Just replaced the 692 servo with a billet servo . It appears to be a brand new unused Sonnax . Used my stock servo pin with the stock inner piston , cushion spring , cushion spring retainer and stock return spring ...

Going to replace the 692 servo with a Sonnax . Will the servo pin sealing rings for a 700-4r fit a 200-4r ? When I built the trans 3 years ago i don't recall the overhaul kit having the pin rings .

My tcc solenoid is not controlled by a computer . 4th gear normally open switch locks it up if I have it switched on . Drops out of lockup wnen it drops to 3rd gear . Other than the heat issue will there be any lubrication issues running around town in 3rd gear unlocked ?

Might be a stupid question but please bear with me . . . . been a while since I cleaned and reassembled the valve body . Took the accumulator bushing , valve and spring out for cleaning . When reassembling I noticed the roll pin did not go all the way through the bushing ( no hole in the...

Sure it's been covered before so I hope I don't get tarred and feathered for asking . . . . . Put .500 main & .296 reverse boost valves in my 200-4r last year with the green spring . Small instruction sheet appears straight out of Transgo . Says to grind the 2nd land off the valve "it's...

Just changed the fluid in the KTF . While I was under there I shortened the Sonnax TV plunger spring a tad , did the 700 filter , and blocked the line bias valve . The filter and line bias thing was maybe not necessary but , what the heck . Hooked the gauge up , got it warm , loosened...

Just curious as to why my 200-4r has the ID tag on the wrong side . Tag is green . From the numbers and letters on the tag one source says ( chart ) that is was a 1990 behind a 307 Olds ? An AC Delco Remanufactured stick on tag was near the top of the case and stenciled in large...

Using a Sonnax 700 plunger spring in my KTF valve body with a 692 servo . Bigger boost valves in pump . 1st to 2nd shift is a little late . All other shifts OK . the 700 spring is longer than what came out of it . I know about the long spring/short spring thing . Wanted to make sure I had...

I have a later model KTF . When I tore it down to build it the 4th accumulator was in case first / spring last just like the ATSG manual shows it . I put a B&M transpack kit in it . B&M says flip the piston so I did . It shifts OK but , would I be better off to put the piston back...
