Sometimes I want to switch from D to N when going downhill and also engage D from N while moving. Can this damage my BW65 Gearbox? I guess the push block is there for some reason, but do anybody know this?

I have another gear switch that I could remove the block between N and D if it's not bad for the gearbox. Having the original left untouched.

Sorry for bad English.
Thanks in advance!
 
As far as I understand you shouldn't coast in neutral with an automatic gearbox because the oil stops circulating & you lose lubrication. This is also the reason for disconnecting the propshaft if you have to tow the car for any distance.
 
Thanks for your reply.

I thougt the engine also operated the oilpump in the gearbox. As long as the engine is turned on the oil circulate and lubricate the box. Is there any other reason the lubrication stops while in Neutral?

Thanks!
 
I'm not a mechanic so can't answer all your questions, especially about auto's. As far as I know, you should leave them in drive. Why would you want to put it in neutral anyway? You won't save much fuel. If you want to coast, buy a 3500S......... :;):
 
Thanks.

Sometimes going for long downhills could make it more comfortable in Neutral.
When approaching a crossing could save some brakepads also. :) Naa, don't know, just feels for be able to switch to N sometimes, but don't want to loose the smooth feeling of the BW65.

Anyone know why there is a block between N and D? Is it because of that the gearbox will loose lubrication in N-posistion while moving?
 
Hello JEP,
why would you want to change from D to N, especially downhill, as (technically and legally) you are not in proper control of your vehicle and you wont be saving any fuel either?
Auto gearbox models "run on" when the throttle is lifted in D which will save you fuel whilst still maintaining control if you need to accelerate.
If you need engine braking on downhill stretches you can select 2 or 1.
Am I on the right track, or have I missed your point?
Regards, John.
p.s. Auto models should not be towed for more than ½mile (i.e. only to "bump start") without the engine running - Therein lies the key.
 
Thanks for your reply John.

You're absolutely right, but I just want to know if the BW65 gearbox could take damage switching from D to N while moving. I have noticed in some occasions that I want to go from D to N. Don't ask me why :)
