Default Changing ATF?

2006 touring non-turbo, 98K miles

The manuals says changing atf is not necessary under normal usage.

However, I noticed the trans jerks when shifting from 1st to 2nd gear, other gears are fine.

Another situation is , when I slow down, say when making a turn, then I press gas pedal to accelerate again, the jerk is very strong, just like being kicked by someone from the back.

Is the transmission dying?

Should I change the atf to mitigate the jerks?

any suggestion is highly appreciated
thanks

The jerk can be caused by the transmission being low on fluid. Check yours first with the car warmed up and in Park with the engine running.

If the fluid level is okay, the best course of action might be to take it to a transmission shop where they can do a complete fluid flush of the system. Then assure they refill with only ATF +4 and a new filter. After that, a good shop will be able to wipe the CVI's and do a transmission relearn procedure. They should also check for shavings and burnt fluid residue in the pan.

Hmm... I touch my transmission every 15k. Filter change at first 15k, then flush at 30k, repeat at 45 at 60k and so on. Never had a shifting problem since the ritual

Sounds like you have some bad motor mounts.

It is tricky here.

When I slow down and then accelerate, if I press the pedal very very gently, then nothing happens;

otherwise the gear shifts (I guess it is from 1 to 2), the jerk is strong.

It is basically like the experience when I first learned to drive a manual transmission, the shifting is rough because I can not shift in the right speed and rpm.

Hi 767!

Do you use RTV on the pan? Or have you found anything that works better? Seems like well cured RTV still allows fluid seepage.

Thanks!

Well... I drain before nightfall and in the morning wipe everything clean. Install with RTV. Fill after it cures. Be careful with the bolt torque, 165 in.lbs. (important!) If still leaks, pan is bent!

I may just replace the pan next time I change the filter.

Thanks 767!

Need to use a rtv that is compatible with trans fluid I have read. Also if you clean mating surfaces with certain chemicals. That will cause the atv to not seal. maybe Mel can tell what he uses.
