Conclusion
O.K. Beav,
As you point out the valve does not have to fully close or open in the course of controlling an intermediate level of pressure but is still basically an on off device. I am not about to add any more words to the explanation which has now been fully expanded and should be clear to anyone interested. However I will come back to the question which raised my original interest in the subject i.e. is it wise to entirely disconnect the resistor ? My conclusion is that the resistor circuit should not be left open and that the addition of an extra series resistor as has been suggested is the safest simple method of increasing line pressure if this is desirable. Adding a second parallel resistor to form a voltage divider network to lower the fixed bias voltage as noted by Brian Steel has advantages and is worth experimenting with but requires caution in respect of component current ratings. In the event that I try out some practical experiments I will post the results but here I hope endeth this thread. Trevor.

That depends on who you ask, and how you regard their response. Some transmission rebuilders suggest using a 'pressure riser' in order to raise the line pressure and change the characteristics of the transmission. See this page for an idea: http://www.bulkparts.com/MM007.ASP?pageno=175
Removing the resistor in order to circumvent a slipping shift is just prolonging the inevitable, however it could also be another way of prolonging the life of a good unit. I suppose the question will always be academic, as the life of the transmission is long enough at worst (usually) to escape operating in a closed control setting. Beav |

Beav you are a mine of information,
As you so rightly say, every Thom. Dick and Harry has there own ideas. The difficulty is knowing who to trust when commercial incentives are involved. Thanks for the easy click so have had a look but could not find any technical info. detailing the way the gizmo works. It looks interesting. One always has to wonder with all after market items as to why the original manufacturer did not offer the claimed improvements although where a special application is involved the situation is rather different. Again thanks, Trevor.
