I bought a 2009 Honda civic with 107k miles. I serviced all the fluids. As a pre-caution I sent a sample of the transmission oil to a lab to test it and waited for it to come back before adding the right amount of fluid back. (3.5QTS which drained out). In the lab result everything was normal and standard wear and tear. The fluid could have been used longer, but still changed it, drain and fill at 100k.
However, I feel the Honda Transmission is not very smooth(before/after fluid change). Compared to my 2005 Buick which is far better and smooth at shifting gears. Is it normal or am I just to paranoid? Should I add a quart of Lucas transmission fluid and add a transmission cooler with a fan to help it?
**Used OEM Honda transmission fluid.
P.S. Thanks for answering my question.
DO NOT use Lucas in a Honda transmission!
Change all the engine & transmission mounts first, then check the results.
Listen to @InThrustWeTrust. Do not gamble on the Honda transmission with Lucas.
Is this a CVT or a normal 5 or 6 speed automatic?
5 Speed, automatic.
If the transmission is slipping, you can remove a quart of the fluid and then put the Lucas in. Just hope that your transmission doesn't jerk or skip gears.
so i was changing the oil today and one of the mounts looks like it weak and could be the issue. will be changing that and seeing it solves the issue.
