Hi there, i'm a bit worried my car is automatic, my old transmission was a little bad change fron P to R like 10 sec. to get it lol. any ways here comes what i have. My old transmission each time it change automatic fron 2nd to 3rd, or 3rd to 4th it make a big hit like something hiting with another thing. and happends to when card drop shift down from 4th to 3rd or 3rd to 2nd. So i decided to change my transmission, ok everything know is fine, reverse take 1 sec. to take it and drive to. but it still making the big hit when changing from shifts, jsut wondering it that is cause of transmission or other thing else? like mounts or what? if it mounts how i know its break?? thanks for some help i will aprecciate.

I have the same problem, only from 1st to second above 3500 rpm's. I think it may be a motor mount problem, or a tranny problem. But I think it's mostly a motor mount problem. Get others feedback as though I am not 100% sure.

If its hitting every gear motor mount. Check your rear one and your front dogbone mount those tend to go out.

what kind of fluid did you use, and is it filled with the right amount?

[deevergote]

Change your fluid with some good Honda ATF, and be sure it's the proper amount (if you aren't comfortable doing it, have it done professionally... at least this time, so you can see if that fixes the problem).

Inspect your motor mounts. They are likely the cause. If you see the inside rubber torn in any way, they're shot. Replace them.

A good strong transmission usually will shift hard, and a hard shift on bad mounts will rock the engine.

Thanks for replys, When mechanic change the transmition i didnot see what fluid he use, but i think it was ones from westerauto, i dont think it was a honda genuine one. I will look for a mechanic to flush old fluid for new and check level of fluid, and will take a look at mounts rear and front, Thanks for information.

another check some one told me to turn on car, put at Drive put break and e-brake and acelerate, I see that the all motor from Powersteering to filter KN make like 2" and half of move up, then when stop acelerate it comes back down 2" and half , probably my problem can be mounts. Any way thanks for hint will be doing it today. And sorry about my english not good.
