406 automatic gearbox problems.

Dear all

I have a 406 2.0 auto year 1997. I find that the gearbox when its shifting
has a strange clunk noise for each gear. The box does this everytime and I
was wondering if the box has be rebuild or replaced.

Is this a common problem for auto boxes from Peugeot?

Thanks!

Jim

 

The ZF 4HP14 gearbox on my last 306 had gear change noise since new. The
Peugeot dealer said it was normal until I changed the oil to fully synthetic
transmission oil and the symptom disappeared.
406 gearbox uses a semi-synthetic oil Esso LT71141. I was told it was filled
for life but in the French ETAI manual, it is recommended to be changed
every 60k kms.
Hope this info helps.
