Where is modulator valve s10Hi there,If your transmission is a stock 1987 s10 2WD or 4x4,the transmission is a 700r4, 4 speed transmission w/ Overdrive.(around 1991 the 700r4, was renamed the 4L60, about 1993 became the 4L60E, E for electronic shift.) This transmission did Not have a vaccuum modulator, as did earlierchevrolet 3sp automatic transmissions.

They use a TV cable (Thottle Valve cable) to determine shifting.The TV cable hooks up to the carburetor or injection body linkage -in a (visual way) similar to the older (kickdown) linkages of 3spd automatic transmissions. It is NOT a Kickdown cable.

Proper adjustment IS CRITICAL to the survival of your 700r4.

you. Good luck

If a 1991 Acura Legend is losing transmission fluid but it is not leaking out where could it be going?

If your transmission has a vaccume shift modulator, the Engine will suck the transmission fluid out & sometimes if the modulator is real BAD U will have smoke coming out of the exhaust pipe. If this is an automatic, and the car is blowing some white smoke, the diaphragm in the transmission modulator is bad. If this is the case, you will have to replace the whole modulator.
