I am being pushed to do a chemical "transmission flush" on my 98 Honda CR-V. Is this a bad idea?

Possible bad injector

Back to rebuilder.

Transmission place is not fine. They need to fix it for you.

It is in the relay block under the computer behind the glove box. Most likely the transmission needs to be flushed. As transmission fluid ages it looses its ability to build pressure especially once it heats up. It is possible the transmission may need more but this is the first step. Only use Honda or Honda equivalent fluid as others will likely cause damage long term. If I can help you further, please contact me on https://www.6ya.com/thericepatch

I believe that was the year that they went to an inline filter,, check this link http://www.handa-accessories.com/crvmaint07.html

Shifter in my 99 Honda goes from D4 to D3 without pushing button also. I 'NEVER' recommend flushing transmissions, it will always cause problems. I've been rebuilding transmissions for 25 years now, flushing causes all the buit-up contaminates to stop up the filter, which cannor be changed on Hondas. I have to admit though I get 'ALOT' of work since the introduction of flushing machines. Good luck.

It is best to flush the trans. Lube shops have a machine that does it. The reason, is that there is fluid in cooling lines, rad cooler, and torque converter that does not get changed without flush. My preference is to flush, then change filter.

just do the drain and trans filter, forget the flush, it doesn't replace the filter which is the most important part of a trans service

Has the Transmission fluid been changed every 30,000 with Honda ATF-Z1?

If some one has put in GM Dexron III in it instead, the transmission may not shift properly and it can damage the transmission over time.

Also if some Express/Quick Lub place has flushed your Honda Transmission Dexron III or any type of Flushing agents, it's probally going to have to be replaced. Google "flushing Honda transmission" or MSN under "Express lub Transmission flush Fraud". Those back flow flushers systems damage the internal valves of many modern transmissions, both import and domestic and have NEVER been recommended.

Suggest taking it by a Honda Dealership or a aftermarket Honda/Acura ASE Certified Shop.

Honda recommends Honda ATF-Z1 Transmission Fluid or a Dexron III ATF as a temporary replacement -- which should be flushed from the system and replaced with the Honda ATF-Z1.
