My car: 1995 Volvo 940 Turbo (w/ AW71)
My question is concerning the "accumulator mod" on an AW71. Basically whenever I do anything I like to push it "right to the limit" and use precise measurement. So when it comes to shimming the accumulators and I make them "barely" shorter than the spring using a micrometer, etc and measure everything up and end up shimming them just a hair too much, in theory what would happen?
...Because I did this, changed the filter, gaskets and added all brand new Mobil 1 atf and ended up frying 2nd gear. (Everything was done precise, cautiously and of proper procedure) The results were pretty much immediate upon first test drive. before this, my transmission was working well and holding between the 1-2 shift. Now it does not shift firm to 2nd gear and slips into and during 2nd gear under WOT. Besides that every other gear and shift is nice and firm! Actually, I put the boost back to stock for now and under normal driving and even some spirited driving it feels really great, its actually a shame really! If the 2nd gear clutch didn't 'let go' than it would be perfect.
Can it just be a coincidence that this happened or is it possible I shimmed one of the accumulators (1-2) just a little too much? Thank you for any input on this matter TB!
