Towards the end of the winter/beginning of spring, I want to put a little money into my transmission. Now that I have full exhaust, intake, gears in the rear end (which I understand helps the transmission) and will have a dynotune around Christmas time, I'll be pushing significant horsepower over stock levels. I figure since I'm getting into these power levels, even with a stock converter, the transmission could seriously benefit from a few very minor mods.
I plan on getting a truck 4L60E pan along with a 28,000 GVW transmission cooler. Those two mods I'm definitely set on. I'm closing in on a year and a half and ~20,000 miles since my last fluid/filter change, so I figure I'll upgrade those parts in the process. I also plan on doing a flush this time, not just a fluid change, as there are 45,000 miles on the trans at this time. I plan to simply feed several quarts of ATF through the transmission as a flush - not use a high pressure machine as that makes me uneasy.
Anyway, the question that I'm asking myself is, should I get the aluminum accumulator pistons? They're very inexpensive, so price is certainly not an issue. I have a few questions regarding this mod:
1.) Is this a good mod to do on a completely stock transmission? I'm not getting any other internal upgrades. I do not want a shift kit, I DEFINITELY do NOT want a converter...the trans will be 100% stock with just aluminum accumulator pistons (and, of course, the cooler and deep pan).
2.) Are the accumulator pistons difficult to install? With the pan and filter removed, can they be installed without touching the valvebody? I DO NOT want to remove the valvebody, I don't want to have to drill into anything...I only want to do this mod if it's as simple as taking off the pan and filter and they're simply right there.
3.) Will there be any difference in shift firmness assuming there are no problems with the stock accumulators? I understand that if the stock plastic accumulators are cracked, the aluminum accumulators will add to shift firmness, but will the trans shift firmer if the stock accumulators are in perfect condition? Firmer shifting is definitely a plus IMO
Thanks for any assistance in advance.
