If all the numbers are close you are ok. It looks like #1 is a bit lower than the rest. You should also do a leak down test though.

you think a leak down is really necesary to see wats up with #1? i mean he kinda kept up the second time lol. and i think its strong enough since.....

( if its even relevant ) when i drive in d4 ( auto tranny ) and kinda floor the gas, cylinder one ( gear one ) gives off the most push when shifting into second. it even makes my whole dash kick. its kinda rough. i hate when it does that. ( kinda like if my mounts cant control the engine movement when it makes that first gear transaction. im not sure if that is something with the mount or the tranny itself. all other gear shifts are smooth and dont make my dash kick)

whats up with that. i would really appreciate some help.

thank you guys so far.

thanks man. just wanted to know if i have normal numbers cus i did the test but didnt even know what are good numbers. anyway, engine revs good and idles great so i am assuming its healthy. ( unless anyone else can say otherwise ) cus like i said......


when i drive in d4 ( auto tranny ) and kinda floor the gas, cylinder one ( gear one ) gives off the most push when shifting into second. it even makes my whole dash kick. its kinda rough. i hate when it does that( but oh well what can i do, its engine power i guess ). ( kinda like if my mounts cant control the engine movement when it makes that first gear transaction. im not sure if that is something with the mount or the tranny itself. all other gear shifts are smooth and dont make my dash kick)


thanks.

Ok, the repeat was unnecessary, lol. But...
A) Cylinder one is not gear one. Cylinders are in the motor, gears in the transmission.

B) The transmission shifting hard under hard acceleration is a sign that it's starting to go bad, ESPECIALLY if it's only in select gear(s) and not the rest. So, take it easy on take off. My fiance's Integra does the same thing through first and second, thus we are doing a manual trans swap

C) I would do the leak down test for sure based on cylinder #1's numbers. Best to see if it's a head gasket or a bigger problem, and best to catch it early if it IS a bigger problem.

Good luck! And take care of that [relatively] low-mileage motor! it will treat you well if you treat it well

Your transmission is fine, check the fluid and drain/refill if needed. Honda auto's are hard shifting by design.

Compression numbers look pretty good to me.

lol just learned something.

and i think i will do a leak down in the future. my tranny fluid is new and ive checked it recently and its fine. i cleaned one of the shift solenoids ( the one that i could reach better and it was already cleaned. there was no need but i did it anyway )

well, who knows if the auto tranny is going or not cus its only rough in the first shift all other ones are perfect. btw the tranny has 166k miles on it and the f22a1 engine has 98k miles
