Transmission Flush At 100K ?

don't flush, only drain and fill. per the honda spec. check tegger.com for the honda factory tsb's that re-state this.

Honda dealerships have recommended tranny flushes in some cases where the transmission had begun to give erratic results.. My son had his done rather than replace the tranny, and in his case it worked.

I have never seen a properly done cooling system flush cause any problems.

Plugs are expensive, but eventually you have to replace them. Pay me now or pay me later. Often, plugs run for such a long interval will open up gap, and will deteriorate.. Considering you have 100K on this one, I think your plugs are pretty well amortized.

Unneeded. Just drain block and rad, flush with plain water, refill with genuine Honda coolant, and no other kind.

Unneeded. Just drain and fill with genuine Honda Z-1 according to the Owner's Manual.

Needed. Replace with OEM-spec: Denso or NGK only!

Honda prohibits "flushes" that use solvents. Honda specifies properly- performed drains and fills using ONLY the correct Honda-specific ATF.

The engine may "run fine", but the electrodes are eroded and worn. Spark plugs are a consumable, like engine oil. Replace them before the Check Engine light comes on.

Think of it this way: you got 6 years and 100K miles out of the original plugs. Spend $100 on new ones, and that's $17 per year, or a tenth-of-a- cent per mile.

It's overdue for all of these things. I'd have done the transmission a few miles ago.

Just change the transmission fluid, there is no reason to do anything fancy.

If you have a filthy old transmission that has not been well maintained, a fluid change or flush will move gunk around and may cause problems. The solution to prevent this is to keep it from getting filthy in the first place and you get there by changing your fluid.

When were they last changed? I'd do it now if the schedule says to do it now, because when the car stops running fine is going to be when you're trying to get somewhere important.

Wait for the misfire and catalytic converter replacement before you change the plugs.
