I have a '91 Loyale with a 3spd auto tranny.  Kickdown on the tranny is real unpredictable.  Is it controlled by vacuum?  How do I fix it?

Yes, it is vacuum controlled.

There should be a hard line running up over the top of the bellhousing. Trace it and make sure it's getting a clean vacuum signal.

If the Vacuum lines are good, you might consider this Idea:


Sometimes valve body and internals gets sticky by dirt, gum and varnish from age and old oils, so I Fixed similar issues on my Wife's car by Pouring a can of Seafoam "TransTune" and running it for a While... then Flushed almost all ATF oil out, removed the Transmission's oil pan and cleansed everything I could inside, then poured fresh High Mileage ATF + half pint of Lucas ATF additive.


Kind Regards.

The 3at has an electric solenoid to control full throttle kick down and a vacuum and governor controlled part throttle kick down. If is a part throttle issue clean and smooth up the parts in the governor, change the fluid and check the vacuum modulator for correct function. The method to clean the governor can be found here http://www.indysworl...ovenorclean.htm
