Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Terry H. - Mods causing long term tranny problems?

During the short months that ive had my intake and muffler, ive noticed that the car's shifts have become less precise and sometimes it seems the tranny likes to retard the shifts (keeping them at high rpms and then rapidly moving to the next gear causing the car to "jump" slightly. Im guessing this is because of the slight decrease in low end-torque/increase in high-end power. I really got to thinking whether im going to have problems with my tranny down the road when I went to get my oil changed and one of the service guys mentioned my "cool intake" and asked if "by the way you have any differences in gear shifts/problems, etc". I told him yes, but just barely, and he said well it shouldn't be any worry for me "for now". Should I be worried about future transmission problems due to the modifications i have now and will do in the future? If so, what can I do to prevent these mishappenings?

Im just guessing here but would a Level 10 torque converter and maybe a shift kit help him out guys?

Check your transmission fluid, it may be low, or, it may simply be your transmission's way of saying, "How about an oil and filter change."

start with the simple stuff first.

just an intake and muffler would not increase output enough to require replacing the torque converter.

A shift kit would likely help, provided the transmission is in good condition. But, a shift kit will eliminate the nice smooth shift patterns set at the factory. However, the higher line pressure, greater torque converter lock up pressure and higher flow rates would benifit the transmission in helping the clutches to last longer, reduce operating temps, shorten shift time, and provide firmer off the line performance.

I think Terry H. is the one to consult here.
