My wife has a 2003 Honda Accord LX with the 2.4 engine with 100 K miles on the car. I recently flushed Redline D4 (there is a used oil analysis of this compared with previous run of Amsoil ATF in transmission analysis section) and exchanged with Redline D6 in her transmission at the Honda Service Center. The Honda Service Department also installed a new Honda inline transmission filter ($23) at my request and stated: "I have never changed one of these in my ten years here." The service department also installed a magnefine filter at my request for no extra charge and stated: "this filter seems well constructed and seems like a good idea because there have been problems with the Accord transmissions." I also had the Amsoil 0w20 oil changed with Amsoil 0w30 SSO. The service center took a sample of the oil and I posted this on here as well.
My wife noticed a difference in shifting characteristics immediately the next day. She is an aggressive left-lane driver and felt the car did not respond as quickly and felt a bit more sluggish than before. SHe felt there was a slight delay in response time with downshifting. I also felt a slight difference in the car. The shifts felt "tighter" and the car felt a heavier and did not rev as quickly with the changed made. My dilemma is that my impulsive nature led me to make so many changes at once.
1. The nonrecommended Redline D-6, although I talked with Dave a few times at Redline and while he recommended Redline D4, he emphasized the viscosity difference as being the main difference between D6 and D4-and did allude to different base stocks. However, he did not indicate different frictional aspects of the fluid.
2). I changed the Honda inline filter and put in the Magnefine filter from the coolant back to the transmission. Honda rechecked this a few times and were satisfied the filter was pointed in the correct direction.
3) I used a higher viscosity oil, which may have influenced revving ability. I did have Amsoil 0w30 TSO in her car about two years ago and felt no difference. The only oil I put in the Honda, which felt sluggish was Castrol GC and that was in my Honda which has a manual transmission.
I decided to add lubeguard Black-HFM a few ounces at a time to see if there would be an improvement in overall shifting feel and performance of the car. I ended up putting in nearly 9 ounces ounces and the car does feel more responsive with shifting. I also did a test of downshifting into second gear to make sure car decelerated and the clutch held, which it did. I have the service manual and the shifting points match up with the one's listed in service manual. The car also holds the gear when accelerating rapidly and displays smooth shifting feel. I wonder if Redline D6 has greater dynamic friction than Redline D4. The car still does not feel quite as quick as it did with other combination of Redline D4 and Amsoil 0w20, and am wondering if motor oil made a difference. I would be interested in any feedback or questions people have as the saying: "a little knowledge is dangerous" applies to my decision making in this.
The good news is my wife is talking with me again as she took my credit card and placed me on a revamped budget that does not include buying more oils or transmission fluids. Luckily-I was able to purchase a case of #204 Schaeffer's ATF before the budget cuts if wanted to change out Redline D6.
