Can someone please tell me what the two channels with the check ball locations marked #3 and #4 on the diagram serve? Ive noticed that some shift kits only use a ball in the channel marked #3 ("competition")while others use them in locations #3 and #4 ( "heavy duty"). I have a few more questions but am trying to understand things in order here :thumbsup:

Thanks. Car is a street/strip deal with 500+ horse 406 with 4200 stall 8" converter, and 4.10 gears. Should I leave #4 out? The instructions for the valvebody say use #3 and #4 but Im guessing that this would be for more of a street deal.

In 1982 I broke my transmission.. It was the first thing to go on the car. I had a local trans "expert" rebuild it with what I thought was a B+M transkit. I had an 11" fairbanks converter on it and it had some real crisp shifts. Second gear chirp and sometimes third. forward 20 years... and the trans is tired so I had a local guy offer to freshen it up and add a TCI direct drum and sprag for a good price. He said that he found a broken spring and replaced a "missing one ??" which I now suspect was the 2-3 accumlator spring. Anyway after I got it back it no longer had the crisp shifts so Im stuck with trying to fiqure out what was done in the first place 25 years ago and what has changed on the last rebuild. I have purchased an ATI street/strip valve body and will probably install that later this year or over the winter. It just gets a little confusing in that all of these manufacturers of shift kits have different things that they do. The B+M kit takes out the #4 ball for street/strip applications while the ATI instructions say to leave it in :confused: Its a heavy car with over 500 ft lbs of torque and Id like to be sure the transmission is up to the task.

Yelsorc, Oldani, Jakeshoe.... are you out there?
What are the advantages/ disadvantages of leaving the accumlator springs out? Are there performance replacement springs ( stock or aftermarket) you could reccommend for the above mentioned application?

Tony the accumulators are a shock absorber of sorts, by leaving the springs out I believe they will be disabled (not good in terms of roller clutch life). I belive kits like B&M disable them or block them, TransGo doesn't. I'm sure you've seen the threads on TransGo vs. B&M.

IF you leave the spring out of the accumilator in the side of the case ( 2nd gear) . the piston slams back and forth.

The cover ( round cover) will wiggle around and some times starts leaking. I leave the spring in that accumilator.

TransGo shift kits do block or restrict these accumilators.
