Rough shift when cold
 

Hey Everyone,

I have a '99 Accord with the V6. I recently rebuilt the transmission at 158,000 miles and everything has been working great, and still is for the most part.

I have an odd issue with the 1-2 shift when the engine has just started and is cold. The transmission will slip/hesitate when shifting from 1st into 2nd gear. It's worse when turning out onto a street and accelerating. When accelerating straight you do not notice it, and once the engine warms to operating temperature the issue is completely gone.

I use genuine Honda fluid (although they changed their formula!) and the level is right where it should be. All of the solenoids and pressure switches were replaced when I rebuilt the unit, and all clutch packs were measured and within proper tolerance according to the manual (and by "within" I mean in the middle, not at one end or the other of the spectrum). I am pretty nit-picky too and made sure every nut and bolt was torqued properly as per the manual.


Any ideas would be helpful!

Tough being a nit-picky guy, but congrats on the rebuild.

I'm leery of trying to fix things that are 99% OK, so thought here is -->
install a remote starter unit and let it warm up for 5 minutes before you leave the house in the AM; might have comfort benefits as well.

OK shoot me.

Maybe "nit-pciky" was a poor choice of words! Haha. Let's just say I try to be as precise as possible when building or working on cars. :)

I should also mention I now have just over 169,000 miles on the car since rebuilding the trans.

Transmission is going out...happened on my 01, the diff went out ...eventually it will do it all the time.
