Well, last night I finished up installing the kit or package from RobertP in my 62K miles '95 LX 4.6 Bird
, had the seperator plate with holes drilled for mild settings (and all nicely deburred I will say
) , two gaskets, new style 1-2 and 2-3 accumulator pistons, two springs (brown and violet
) and a filter.
Just so you know, I've put shift kits in many cars and trucks over the years, some called for complete VB
disassembly, new springs here or there, maybe a new governor spring set, etc. Never had an issue with one yet, even did a couple police cars. This was my first in a 4R70W and the kit idea sounded appealing, and by getting it I figured I could check his holes and there'ld be two sets of eyes checking the drilling where as if I done mine, no one to review my work? Price was good, especially when I didn't have to gather stuff or drill the plate. It was the right decision I see.
Car up on ramps, then jacked up at frame a little and stands in place, in park, brake applied. I used the hose in a bucket from top rad coller fitting to pump most fluid out of the pan.
My original 1-2 accumulator
had only a bottom spring and it was in 4 pieces.
It started shifting harder a few momths ago and I suspected the broken accumulator spring which is when I ordered the package from Robert to get the new pistons and predrilled plate to.
Bore was chewed up a little all around in a straight line where the spring pieces were pushed against it when the accumulator was pushed down under pressure.
I installed new parts choosing to use both the new brown spring on top and violet spring under the accumulator. I also cleaned the bore and worked the scarring some with very fine sand paper. I believe the scarring is below where the piston works so no harm.
with spring was removed, just put new style piston back and the retainer.
Swap plates, and removed 8 balls and weight thingy and sprayed VB
and let dry, put 8 balls back where they were supposed to be ( I marked the old gasket with silver marker.
) ... and weight thingy near trans filter hole. Put everything back together using the article.
Torqued the 25 - 8mm bolts and that one 10mm bolt to 90 in/lbs (that's 7.5 ft/lbs
New filter install, etc ... Used 9 quarts.
Hardest part was getting my snap ring pliar tips to fitt and hold onto the inside snap ring in the 1-2 accumulator when removing it. My light weight pliars not stout enough, so dug and found my old KD snap ring pliar set and tips. Took two tips with broken tits (never discard tools, even parts may someday be made to work
) and rounded the 6 sided tips to go in the snap ring holes.
Worked on tips again so they'ld go deeper in them holes while I had snap ring loose and could "fit" the tips. Piece of cake when putting back, used bottle jack and piece of short pipe as spacer to press spring - piston - spring - retainer back.
Test drove today, WOW .... glad I put both springs in the 1-2 accumulator!
Would not want it any harsher under WOT! Light load driving, very smooth but noticeable shifts. Heavy throttle and the shifts get harder fast.
I like it.
I also noticed that a rattle or buzz almost at idle in neutral is now gone
. I am pretty sure it was those broken spring pieces being stirred around when no pressure on the piston above them? Quiet in all positions now
I am really pleased!
Just thought I'ld post an easy to find followup.
