Slowing down before shifting

[replicator]

My automatic '00 LX slows down before shifting gears 1-3, could be normal I suppose. The issue diminishes, and eventually disappears after the car has warmed. It only has 79k miles, so I doubt it's a mechanical issue. No weird sounds or clicks during regular shifting.

Thoughts?

Do you mean it shifts gears at higher rpm's (later)? or are the mph are going down before it shifts?

Normally most auto's, when they are cold, stay in gear longer to heat up the transmission fluid faster.

Yes sir, typically at higher RPMs it's less noticeable. At low RPM's it slows down for a second before shifting. Barely noticeable, but I'm very aware of things in general.

Sticky valve perhaps?

 

[replicator]

Checked, valve (butterfly?) does not stick, and is in a clean condition.

 

[joeshmo]

Which valve are you talking about? I'm talking about the tranny valve, not the throttle valve.

 

[replicator]

Not sure what that looks like, how easy it is to access, or how it looks :[

 

[joeshmo]

You probably won't be able to check the valve body. I'm not sure about these honda autos, but I know for my chrysler one could check for transmission codes with the proper reader. Have you checked the trasmission fluid?

 

[replicator]

Yeah, the color of the fluid is great and it smells healthy (no burning smell, fresh transparent dark pink)

 

[joeshmo]

How is the level with the transmission warmed up?

 

[replicator]

I'm not sure what you mean by level, level of the fluid? Looks dead on the top marker, which is ideal. It shifts seamlessly warmed up too.

 

[joeshmo]

Huh, I wonder if it might be as already mentioned just a function to warm up the tranny fluid more quickly/

Yep, as time flies, shifting becomes smoother and smoother, and after about 10-15 minutes of driving, it becomes seamless. Sure hope that's all it is. :]
