Update: first drain and fill fixed the problem instantly and completely plus it does not shift as “clunky” I’m going to do two more though just for good measure!! They will be thrilled!
How much was the jiffy service, cheaper than the dealer?So i called the local jiffy lube, and they use synthetic Versa trans LV ATF...(https://phillips66lubricants.com/product/versatrans-lv-atf-transmission-fluid/) BUT they told me they will not touch it because of the TC shudder. Maybe i should of not told them that part... But they extract from the fill port, then add the fluid, and said its "kinda" like a flush.
Next i'll call the dealer next to see what they have to say.
That has been serviced before. Usually the first fluid change has globs of goo on the plug.Doing the 3x3 now. It’s definitely torque converter shudder , as if you put it in d3 it does not do it. I drove it and experimented with different throttle inputs and using d3 and it will not shudder if it’s in d3 no matter how little the throttle input. Also if it’s shuddering and you click it in to d3 it goes away instantly, or if you jab the throttle quickly it goes away. It also does it in first - third like clock work in normal drive. No shudder in d3 on same road and same inputs. The fluid looks black and there is a ton of sludge on the magnetic drain bolt. It’s definitely looking original. And for your guys here are some pics
Yeah, I've seen more even on cars that have the fluid swapped on a routine basis.That has been serviced before. Usually the first fluid change has globs of goo on the plug.
I was going to tell you that a single drain and refill would take care of it but I wasn't sure if I was confident enough given it had 170k miles. No harm in doing add'l ones either... Like @The Critic said though, that fluid has probably been changed before, probably a previous owner (?? you don't say if they're the original owner).first drain and fill fixed the problem instantly
You might be right. They only owned car for 7 years and 150k miles. So that leaves 2.5 years and 30k miles unaccounted for. They personally never did the transmission service but are a extremely gentle driver with most shifts occurring at 2400 or below. Most likely the dealer did it before sale around 30k. It was still long over due, and I think the computer hides bad fluid by adjusting shift points and slip ect so most people are not even aware until the fluid breaks down past a point and the tc starts shuddering because of bad fluid. Even with the old fluid shifting felt acceptable minus the tc shudder. But with the new fluid i noticed it shifted even more “direct” with zero shudder.That has been serviced before. Usually the first fluid change has globs of goo on the plug.
The amount of new fluid vs old fluid that is calculated is only theoretical (based on math), not based on physically measuring the fluid. If you measured or analyzed the fluid, I don't believe it will be as "new" as the formulas say. In reality though, it absolutely "helps".but if you do the swap concurrently, running the motor and shifting the gears for about 1 minute 45 seconds, that should pump the new fluid in and leave mostly old fluid
How long did you run it between drain and fills? Why not just pull a cooler line and refill it as the trans is pumping it out?Okay, so DW-1 fluid it is, from the dealer! Im going to take this job on, and do a 3X3 method for them for 9QTS total then i know most of the fluid is changed, and its done to spec and the correct way.. I informed them already honda recommends 30-60K transmission fluid changes, and they are way over, so if something get worse, we tried, but changing the fluid via drain and fill 3 times, when done correctly should not blow the transmission up, unless its already on its way out..
Because Honda says to do multiple drain and refills instead of a flush.How long did you run it between drain and fills? Why not just pull a cooler line and refill it as the trans is pumping it out?
Job is done. Vehicle owner is happy.Why not just pull a cooler line and refill it as the trans is pumping it out?
If the ATF is maintained and changed on a decent schedule, based on many instances of people that changed them said they wasted their time and (small amount of) money. If the fluid history is unknown, it may be worth changing but if you keep up the replacement of fluid, don't bother changing it again.I think that those tyranny’s have an external filter that can & should be changed. YouTube would be helpful for this.
