I think this is the no reverse cause.RRPhil said:I haven't heard of particular problems with solenoids, although the 5L40-E does have individual fluid filter screens on some solenoids which can become blocked I believe.
I’m afraid I can’t tell from the very limited information I have if the three shift solenoids or the main pressure control solenoid have built in filter screens. I only know for sure that the torque converter LUC one does. As you say, the breaking up of this filter can give rise to a loss of drive in reverse in the 5L40-E. There are certainly two further small screen assemblies installed in the valve block itself.umitbat said:I think this is the no reverse cause.
Will this have affect on drive?
On '02-'05 L322s the 3.0 diesel & 4.4 V8 radiators have different part numbers and the transmission fluid coolers are quite different for each. For example, the thermostatic control of water flow through the fluid cooler is internal on the diesel cooler but external of the petrol-engined one. However, the clogging up of the radiator through sediment & corrosion and the subsequent starvation of water flow to the fluid cooler you would imagine would be a similar problem on both models. Having said that, I can’t recall anyone having raised it (i.e. fluid temperature warning) as a problem for the diesel on this forum – though countless people have mentioned it for the BMW 4.4 V8 version.umitbat said:Are there any cooler radiator issues?
I know many VW cars experience this.
