You stated that you changed all of the oils. Does that include the transmission fluid? If so, what fluid did you use in the transmission? I know of many Honda automatics that when filled with a "normal" automatic transmission fluid are very prone to failure.

 

what transmission fluid would you recommend?

 

The D16Y5 will fit any trans the Y7 or Y8 will fit... the D16Y5 is almost the same as a Y8, and can be changed into a Y8 with an ECU and swap of the vavle train in the head...

As for auto trans fluid, I dunno... the only auto i ran was mrs car, and i dont rem what fluid i used in it...

sloopy.

 

Wasn't Y5 a CVT? I remember a while back, that Honda warrantied them longer than typical. It's worth a try.

 

Sloopy is right, there are many options when it comes to replacing the transmission. As for the fluid, Honda ATF is the only fluid that is recommended in any modern Honda auto, although i believe Valvoline Max-Life ATF has compatible additives and Valvoline claims to cover all of Honda's requirements.

And if Richie is right and it is a CVT, the fluid requirements are much more strict and if it is failing i'd definitely recommend swapping for a normal auto or a manual.

 

if you have little cash left buy any d series auto trans 96+, there is plenty out there doing
auto to manual swaps that get rid of the auto trans for fairly cheap. I gave mine away lol

 

damn, where were you when i had to get one for mrs car? I had to shell out $80 and drive 90miles to get one...

OP: The D16Y5 is a good engine, I have had on in my car for 4 years, and have over 75,000miles on it, and it still runs fine... and since it is basically a Y8 (the head is the same casting), you can use anything for the Y8 on it...

I went to the dealership and i got the following codes p1300,p0301,p303,p1399,p0170

303 mean cylinder3 misfires
301 mean cylinder1 misfires
others one are for random misfire
i don't know what 170 means

my question is this if i find a transmission from y8 and replace it will it fix this problem? i am really really short on cash right now

This is the transmission i FOUND:

P0170 is a fueling issue, it means that the computer can't compensate enough to make up for a lean or rich condition. Maybe replace the fuel filter as a start. Possibly also look for fouling on the oxygen sensors. Were they extremely white or black when you replaced them? Same with the spark plugs, did they seem sooty (white or black)? It seems that it's also common for that code to present itself when there is a vacuum leak. Check all of the hoses on the intake manifold for cracks or tears also. (PCV, brake booster, fuel pressure regulator, purge solenoid, etc...)

 

judging from the OP and my experience the trans has no offect on a bouncing idle like that specially in park/neutral now i may be wrong since i dont ever work on auto cars or have any experience with them. someone correct me if im wrong but id say the trans wont fix your problem

 

Exactly why I'm headed toward diagnosing the feeling issue.

 

98 civic ex automatic transmission

will this transmission fit a d16y5?
-i am going to change the fuel filter
-change transmission fluid

 

That transmission should have no problems bolting up to your engine.

 

if your having that many issues with cylinders then im almost 100 percent sure thats the distributor, all the sensors you mentioned are in there. All the readings that its gettin are out on watch.

 

I believe the crank position sensor would give him issues like this and in the timing cover.

 

The transmission in fact,a cvt,, I have one in a hx I just bought myself, and unfortunitly the mount system for the cvt is intirely different so a normal auto will bolt up but wont even be close for the mount fitting the chassis

 

Its not your trans making it do that. It sounds more like a vac leak to me.

 

Intake manifold gasket. my car is doing it now. spray some carb cleaner around the intake manifoldgasket. if it steadys theres ya problem.

^ This ^

And as I have no hands on experience with Honda CVTs, I can only assume that the engine bay itself is the same for all models. So the mounts for the auto should bolt to the "frame" the same as the CVT mounts do, you would just need the appropriate mounts for whatever trans you choose.
