After reading this thread, I thought about the HKS ALC II or Auto Line Controller used in my 300ZX. It is suppose to increase and controller the automatic transmissions line pressure for firmer shifts and improved performance. It really works well. If the HKS's ALC II was available for the 5th Gen Max, the problem might be solved. If enough people approach them with this, they might see the demand is worth the R & D and production? See link:

This might get HKS to produce an ALC II for the Maxima.
I'd like to see this happen before I start having any transmission problems.
Plug-in interface with factory A/T Control Unit of the computer controlled automatic transmission on the ‘90-’96 Nissan 300ZX. The ALC II is designed to maintain constant line pressure within the transmission for consistent, crisp high performance shifting. Should the pressure begin to drop within the transmission, the ALC II will signal the factory A/T Control Unit to increase line pressure and maintain it at that level.
