If the transmission oil got really dark and had particles, it's mostlikely the particles found their way into the valve body and are currently causing a lot of problems. Your gear box is less than 50k you should consider replacing it.

Thanks, Gazzus. I was thinking the Atf needed to be changed cos of what I considered dirt inside it. Didn't think it would result to this. In the meantime, can I change the ATF and see if it will pick again?

GAZZUZZ:


you can try, use honda DW1 please

Pls Gazzus jus following this tread enlightened me about something, I changed my mitsubishi endeavour gear oil with the recommended SP 111 but the mech never mentioned changing the filter to me as well! Over a month ago,pls any qualms? Or can i still go ahead nd change the filter?

@carblognaija@ Gazzus, thanks so much for ur responses. It never occurred to me that nozzle issue could affect gear performance. Nozzle was serviced as the car was misfiring, too. Pronto, the gear picked. This is a lesson for me all d same.

mind u there is no relationship between the injector nozzle and the transmission , the issue was initially that ur car cannot be rev to the level required for your gear to shift

carblognaija:
First of all, I don't recommend using Seahorse. Since you used it for sometime, you've been lucky but not so lucky. I always tell people when it comes to gear box use the recommended oil by manufacturer no matter the vehicle. Look for the manufacturer's recommended gear oil. Its normally written by the side of the gear oil dip or spoke. If you don't see it the best bet is to go for original Honda gear oil for your car.

Secondly, since you noticed dirt, changing only oil without the gear oil filter makes no sense. Please you need to go back, get a good oil and change the gear oil filter. Gear oil filter is between 3k to 4k brand new one. The mechanic will remove the old one. Use it to go get a new one.

I am sure once you change the oil and gear oil filter, the problem will stop. Again some cars have selector wires or hook inside the engine and some mechanics may remove it when working and forget to set it back. This can also cause some problems during gear selection.

I don't believe this is a gear problem for now. Finally, there are some jobs you don't give to mechanic without your presence in the mechanic workshop. Anything that has to do with engine and gear box i recommend you be there no matter how busy you may be. you are not the one doing the work but you can take decisions concerning your car there and test the car immediately its finished.

Please let us know how it goes

I'm tired now. Changed the oil to recommended one. one minute it works fine, next minute the problem is back. it will rev with no corresponding increase in its acceleration. No gear shift. it only works fine for like 5 mins if the vehicle had been previously parked for some hrs.

ZIMDRILL:


looks like your gearbox is gone, does it looses gears after warming up ? ( it only works fine for like 5 mins if the vehicle had been previously parked for some hrs) that suggest that your clutches are worn out and when the oil is cold they manage to engage into gears but once the oil has warm up they slip and they wont engage into any gears
