Is that for all hondas or some? I have a 2012 honda civic with 107000 miles on it that I was told by a mechanic needed a flush and fill trans service.

Did u find the solution to the r problem ???

Surely he’s going to top off the fluid that is lost when changing the pan. Maybe he thought you meant “flush” the transmission fluid, which is different than a simple drain and refill. I would ask to clarify.

If the gear oil is black and/or gray, I’d change it. Manual transmissions will slip if the clutch is going out, yes. This tends to start in 3rd or 4th gear when you’re under full load. As the clutch wears more, the slipping will get progressively worse.

I don’t know if the old fluid will affect shifting. When you drain the fluid, look for metal in the transmission and on the drain plug. This is a good indicator that something bad has happened to the internals of the transmission. If you find a lot of metal (and I suspect you will, given the gray tint to the oil), I would start thinking about a transmission replacement or rebuild.

I have no idea if Lucas Transmission-Fix will help. My guess is it will be a band-aid at best. Personally I would start by replacing the transmission fluid and go from there.

While you’re in there, check your clutch fluid and make sure there are no leaks. Your first few symptoms to me sounded like air in the clutch lines. The fluid level should not be dropping over time.

At first shifting problems would began once the engine got warm after a few miles. Then It got to a point where I cannot shift into gears at all after cranking the ignition…

So, I replaced both Clutch Master and Clutch Slave Cylinders and bled it to where my clutch is nice and stiff.

After a few initial very short test drives in my apartment complex, it appeared that Shifting had significantly improved 100%. Then, not long after, that same day, after going to a near by Kroger Grocery, on my way back home, the problems returned (i.e. could not shift into any gears, and had to shut the truck off in order to shift into a gear, and I rode 2nd gear all the way back home. When I got home, I did smell that burnt rubber smell again coming from under the hood, in the vicinity of the clutch.

Yesterday I checked the transmission fluid and after partially removing the “fill” screw, fluid did come out, but it was a blackish-grayish color, but I could still slightly see through it. I could also see particals in it.

Noises: Ever Since I bought it “used,” when I press on the clutch I’m hearing a knocking noise and separately I’d hear a loud whining but didn’t affect my shifting or acceleration.

It’s high mileage w/ 350K+ Miles and I’ve had it for seven years and never changed the transmission fluid. I also didn’t know the previous owner very well.

I was going to bleed once again and disassemble my shifter-tower for any wear.

My Question is, Should I drain and fill this dirty fluid? And will manual transmissions slip like automatics? And will old fluid cause a lack of shifting? Would Lucas-Tansmission-Fix (Lucas) correct the issue? Should I drain all the fluid or just enough add the Lucas?

Were the fluid lines loose? Could the smoking have been caused by leaking transmission fluid, or spilled transmission fluid from the initial fluid change?

How many miles were on the transmission when they flushed it? Why would they suspect you need a transmission flush when your car is overheating? Although automatic transmissions typically use the radiator to cool transmission fluid, those two issues seem completely unrelated to me.

I’m pretty skeptical of this shop, given your description of the situation. I might consider looking elsewhere next time you need maintenance.
