Why the BG machine holds 14 quarts to try to get as much of the 11 changed.
I'm being pessimistic at 90%.
That being so, what effect would it have on a synthetic changeover - having > 90% synthetic ATF mixed with < 10% conventional ATF in the transmission?Q45tech wrote: 90% or 93 or 95% because you never know how much old ATF leaks thru the system internally.....................100% of the ATF doesn't flow thru TC and out the cooler line in a single pass.

Local BG distributor told me 95% - 98%.qship96 wrote:90% fluid change?
Clogged screen will starve the planetary gears.goody94q45 wrote:After cleaning the filter and changing the fluid, the large bottle of Lucas Transmission Treatment might be very helpful in this case. It doesn't cost much more than a quart of ATF and will help with slipping and shifting. I know from experience that if ithe tranny's starved for fluid (about 1 1/2 qts. low) it will not shift out of 1st. Good luck.
I guess I did ok then last week by 6 manual drain/refills timed at 2.0 minutes,with 83-85% of the 25,000 mile old redline d4 atf replaced by new d4-and saved the $100+ by skipping the machineQ45tech wrote:90% or 93 or 95% because you never know how much old ATF leaks thru the system internally.....................100% of the ATF doesn't flow thru TC and out the cooler line in a single pass.

Don't confuse gravity flow with a mechanical exchange under pressure. One works, the other just gets the less broken down fuild out and leaves the worst contaminated fluid and detritus within.qship96 wrote:I guess I did ok then last week by 6 manual drain/refills timed at 2.0 minutes,with 83-85% of the 25,000 mile old redline d4 atf replaced by new d4-and saved the $100+ by skipping the machine
Brian,are we really going to go through this bullsh*t again? Q45tech IS THE ONE WHO ORIGINALLY POSTED THIS METHOD as an effective way to replace the majority of atf w/o using a machine!maxnix wrote:Don't confuse gravity flow with a mechanical exchange under pressure.

You might have saved money on the short run, but you cost your car transmission life on the long run. If you read Q45tech's posts, you will never find a recommendation to drain and refill for that very reason.
