Can a clogged transmission filter cause shifting problems?

Shifting Issues

When the transmission fluid isn’t clean or is blocked by a clogged filter, the internal components won’t have the lubrication they require to function properly. This could lead to shifting issues, grinding gears, slipping transmission or other common symptoms of transmission problems.

Can a bad EGR valve cause shifting problems?

A leaky egr, which allows exhaust gases to recirculate to the intake and thereby reburnt by the engine, cause a low vacuum indication, causing the transmission to shift later nad firmer. Disconnecting the egr( and plugging the vac line) eliminates the vacuum leak.
