My 727 automatic trans is leaking at the speedometer cable. Took the housing with markings 21/25 to local trans shop old-timer that use to work on these replaced the seal, acually put 2 seals in the housing. drive it 25 miles and it still leaks. trans shop guy thinks the housing should have a gear in there with 21/25 teeth. even though year one lists only 1 housing. Year one shows gears starting at 24 teeth thru 43 teeth.
My gear is a RED 36 teeth and is acurate
ANY ONE OUT IN MOPAR LAND HAVE ANY INPUT on why this thing leaks????
