Anyone with experience with these transmissions?

my Mini have the aisin TF-60SN with 110k miles on it.

transmission was rough, slipping and kicking on reverse 2 to 3 and 3 to 4.

I decided to go ahead and replace 6 solanoids on valve body also replaced transmission pan that was rusty.

Now gears filling smooth except from 2 to 3, it doesn’t kick anymore but it still a bit of delay. It only happens in automatic, if I go trough the gears manually it doesn’t happen.

what could be wrong?

 

No hands on experience but I’ve been gathering info on them over the years in case any issues pop up with mine. The valve body might need some adjusting or the fluid level could be wrong. Was the fluid within the proper temperature range when the level was set? Also, this page has info on various shifting issues and the valve adjustments which might correct them: https://www.sonnax.com/tech_resource...n-fwd-6-speeds

 

Thank you for the information!!

 

Anyone knows how to check ATF temperature on inpa?
