A common problem with the 6-speed automatic transmission Aisin Warner (TF-60SN, TR-60SN, TF-80SC, TF-80SC gen2 series) is the wear of the batteries and the holes in which they work, the symptoms are:

•      Gearshift delayed
•      Gearshift slippage

Operating a vehicle with such a malfunction will result in burnt clutch packs and damage of the brake band.

Please note, the installation of such a valve allows you to raise the vacuum by 3-7 inHg. This is not a universal method of repair, and if there is critical wear in the valve body channel, it will not help you, in this case it is necessary to install an oversized valve::
