my car just recently reached 100k miles. is it absolutely necessary to get my transmission and antiffreeze system flushed like the shops recommend?
i would...might save you down the road.
hell my car only has 50-60 on it and i had a rad flush the other month
I may run 18s, but I can do your taxes in 10 seconds flat.
so which of the flushes do u suggest?
both. regular maintenacne is always good.

I use on a very regular basis(in my own cars as well) and really believe in the flushes available today. I use and like the ones fron BG. I STRONGLY recommend a coolant flush, DexCool is funky stuff and I dont recommend letting it go anywhere near the stated 5yr/150k mile life. As far as a trans flush....again I like the BG ones, it connects inline with the cooler lines and the trans actually powers the flush, there is no external power or pressure source like some other flushes, Ive never seen a trans damaged by this method. However I do NOT recommend using the cleaning agent in the kit on any trans with over 75k miles on it....it cleans so well it can remove too much varnish/buildup and increase tolernaces in the trans. If you get this done just ask the shop to not use the CLEANER portion of the kit....they wont mind(one less step). I REALLY like BG flushes...they work. Wynns also has products I hear good things about. Also dont forget about your brake fluid!!! even though GM doesnt actually have a maintenance schedule for it, nearly every other car maker(and fluid supplier) wants you to do a brake fluid flush(just a really thorough bleed that gets all new fluid in the system) every two years. I recommend it, and youll feel a difference.

thnx guys. i appreciate it, i guess ill get those flushes with my alignment. btw, wut exactly is BG, and wut do u mean by cleaner agent and cleaner? could u help me out a little more so that i can know exactly wut to ask? thnx
brake fluid flushes are a very good idea. dot 3 readily obsorbs moisture and decreases the boiling point after time. and the haynes book says that whatevers in the tranny pretty much is staying in the tranny. pretty much to flush out a tranny good you'd have just drive it a little bit. for any fluid flush the hotter the better. with an auto tranny your supposed to put it in gear and then hold the brake and hit the gas. let the tranny do the work in there as far as breaking down gunk. with an manual trans pretty much driving it every day will break it down because they work on a splash type deal in there with the fluid. but what is the recommended fluid for a trans flush? i'd like to go all synthetics in my car. when i switched to synthetic motor oil i noticed almost a hundred extra miles per tank.
Z... go to bgprod.com to see what BG has to say about themselves, they are just one of many companies who make car maintenance products and happen to be the one I prefer.
The trans flush is a multistep process that starts with the addition of a cleaner to the trans fluid, I dont use or recommend this fluid in cars with over 75k miles. So whats happens during the flush is that the trans fluid is brought up to a nice warm operating temp(100-180deg usually) a machine is connected inline(in series) with the trans cooler line. with the engine running at idle and trans in park the pump inside the trans circulates fluid normally through the trans and cooler, however when it goes into the flush machine it enters a sealed waste fluid reservoir, this res. then pushes fluid out of the new fluid reservoir and back into the trans cooler. The machine holds 16 quarts of fluid and continues until the used side of the machine is full and the new side is empty, Since the 4t40/45 holds only 12.9 quarts of fluid and the machine holds 16 you can see that this is a true full flush and not merely a fluid change like dropping the pan is, dropping the pan only lets you change 6.9 quarts, only a little more than half!! This is also true of the "exchange" machine that suck fluid out through the fill hole/dipstick.

I have always heard that you don't ever have to do anything to manual transmission fluid unless its leaking??

i have right at 101k miles now so should i still get it? and basically i guess ill get the brake flush also. anything else u suggest to go along? o btw, i want to switch to synthetic, are there any special steps that i need to take or do i just switch it out?
Silver.... You cant really flush manual trans like coolant systems or autos, but I highly recommend changing manual trans fluid, as often as you can manage/afford. no fluid lasts forever.
Deuce, preventitive maint enance is the way to go, I never shy away from it, just like I said ....avoid the cleaner step in your trans. As faras synthetic goes....justdrain and fill.
