transmission fluid

[TOMMYMCA79]

Im havin a bit of bother regarding a salvage automatic gearbox being fitted to my mercedes v230 auto.

The mechanic has informed that he has used 5 litres mercedes fluid and 5 litres of dextron 3 fluid.

The gearbox will not engage drive and I am wondering wether the choose of using different fluids could result in this problem.

Sussex automatic specialist thinks that could be the problem as dextron 3 is not a syntehic oil were as mercedes oil is fully syntheic

any suggestions gra

Walk away from this 'mechanic' - he is screwing up what's left of your g'box! I made it quite clear in my previous post to use SYNTHETIC OIL for the refill - does this guy understand what you are telling him, why the hell is he mixing the oils? [:(!]

All auto trans fluids are synthetic. But why is he mixing? Just use original Mercedes and you should be fine.
