#4 of 7 Filings in auto tranny by easypar

Well in my long life I've always gone by the "how much is too much" rule on metal bits in the tranny fluid. I think "some" little bit is considered normal. Big chunks, whether steel or aluminum spells trouble.
 
If this work was done at a "transmission specialist" type of shop I'd be wary of the diagnosis, the industry doesn't have a reputation as straight shooters! OTOH, if you've been experiencing a lot of tranny troubles you may be right.
 
I've often been as concerned about burnt/darkened fluid as about little bits of metal.
 
Has the tranny been serviced as called for insofar as changing fluid and filter?

Thanks for the prompt response. The only difficulty I have is that a rebuild has been quoted at between P20 000 and P50 000 - whereas a second hand replacement has been quoted at approximately P10 000!

We have just performed a transmission flush. Will take you advice about careful observation and a redrain.
I bought the vehicle second hand in great condition with 40 000 km on clock - it now has approx 60 000 km and has not given a days trouble - in fact the car is going like a steam train (other than the 3 brief occassions outlined in my post).
I am not aware of the transmission fluuid being dranined before but doubt it due to the low mileage.
60 000 kms on car.
20 000 kms since last full service although I had a minor service about 10 000 kms ago.
Thanks again for the response.

Thanks for the response easypar - to the best of my knowledge this is the first time the tranny has been serviced - car only has about 60 000 kms on it and is in very good condition.
 
Is there any chance that the initial problem of gearing down may be an electronic issue and have nothing to do with the iron filings in the fluid?
