My c4 transmission is leaking a substantial amount of ATF, and I dont recall an o-ring seal for the speedometer cable wondering if this would cause a leak this major. My other thought would be the coolant lines. Any thoughts or suggestions would be greatly appreciated.

 

check the "Box" on the bottom of the car midway along the bodu, not sure what its called :P. Mine is leaking pretty fast from there, eg 5+ drips a day. im pretty sure i read somewhere that the gaskets on that werent made to hold pressure so overfilling the with ATF would cause higher pressure making it leak.

 

Mine is a little more than 5 drips a day, I havent jacked the car up and taken a look under it yet to see where it is coming from. Just wanted some input on places i should be looking for besides the tranny pan, i have already replaced that gasket.

 

C4s leak at the kick-down lever, the shift lever (called a manual lever), band adjuster bolts, dipstick tube and speedo. They can also leak at the converter seal and extension housing seal.
When you get under the car and actually look at where it is leaking you will probably get more concise answers.

 

jacked it up today and took a look. seemed like it was leaking mostly from spedo cable, alot of ATF on the tranny mount and that area. I took out the spedo cable and did not have an o ring on it. Ran to the local parts store found an o ring that fit and stuck it back in and cleaned up the underside. hopefully that will take care of the major leak i had. Thanks for the input everyone

 

Excellent i would degrease the hell out of it to see if it continues
