automatic 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

I may be wrong but I dont think you should ever mix ATF of differing brands. If I am right then your mechanic has some embarrasing explaining to do, plus maybe a replacement box at his expence.

I agree with Ian re. mixing ATF. However in fairness, I think had the 'box been sound it would have shown SOME response, regardless of the mixed oils, at least initially?

The box is probably faulty, or fitted incorrectly, the oil would not have an immediate effect, it is more likely to affect shift quality rather than cause failure
