The position of the selector valve is determined by which source has the most pressure. If the engine is running and the pump is off, the fluid flow is routed to the transmission cooler and back the the transmission. If the pump is running and the engine is off, the valve routes the flow from the pump back the transmission. If both are running, the source with the highest pressure will determine the valve position, or if the pressures are roughly equal, the valve will allow some flow from each source. In any case, the transmission always gets sufficient flow to keep it lubricated. Some times in sub-freezing weather, the cold fluid when the pump starts up doesn't allow enough pressure to trip the pressure switch, and the dash alarm sounds. When that happens, I just start the engine with the remote start fob and let it time cycle once. By then the fluid is warm enough to flow at the higher pressure needed to keep the alarm off.

Dutch, I actually did call the tech (Terry) at Remco again this morning in the end as I wanted if possible to push on with the job today. I believed I'd got my head around the system in the end, and he confirmed I had. Of course, you are totally correct in your explanation, thank you.

He stated the maximum line run should be 8ft and I knew I was over that as I had simply extended the existing plumbing rather than rip it out and re-do it when relocating the pump (lazy). So I ripped everything out this afternoon and guess what I found (apart from long hose runs). The original installer had wrongly used 3/8" hose for the pump output side and 5/16" for the input.  When I'd pulled the old pump out from between the radiator and bumper, I had to cut the hoses as they were stuck fast on the connectors. I never thought to check if the installer had put them on the right way round, and just extended them up to the firewall to the new pump location. The correct sizing is 3/8" input (from the Remco 3/8" connector on the transmission pan to the pump) and 5/16" output (from the pump to the selector valve which has 5/16" connectors).  They had fitted them the other way round. So when I extended, I connected as per Remco specs, but unknowingly connected the wrong way round.  I suspect the installer realized this after fitting the hoses and instead of rectifying it, plugged the quick connectors round the wrong way on the pump. I had no chance. ::)

Anyway, I'm reasonably confident it'll be up & running tomorrow. I'm relocating the selector valve to beside the pump so everything will be short runs, clean, dry and accessible.  That's the hope anyway....

Dougie.

Sounds good, Dougie! I hope it all works out well for you. We've been very pleased with our Remco setup installed on two toads so far.

All is well.;D  Connected up the selector valve, started the engine (no leaks, hoorah) and got a good continuity reading through the pressure switch. The hoses that should've got hot, got hot; the others stayed cold.  Switched off and tested the pump.  Again, good pressure continuity and the other hoses that now should've got hot, got hot whilst the first ones cooled.  Wired in the pressure switch to the 6-pole socket, connected up to the RV, took a deep breath, and..... the controller liked it. 8)

I fitted the inline magnetic filter between the transmission and the selector valve which may do some good to the tranny generally.  I'm obviously happy to have it all working again and to have learnt some good things along the way.  I like the way it makes you less frightened to deal with stuff too. So as ever, big thanks to everyone for jumping in with the help!

Afterthought
As I lay awake at 5:00am this morning trying to ignore the thunderstorm, it occurred to me that after having towed with the engine idling, it would be useful to use the pressure warning system under those circumstances without the pump running. Simple solution - fitted a switch in the engine bay to stop power to the pump (e.g. if it goes faulty again) but leave the power to the pressure switch. Result is the monitor in the RV does its job with the car engine running so no more worries about it stopping without warning.

As a postscript, I had a surprise call this morning from the Remco tech asking how I got on with the job.  He was genuinely pleased I fixed it, and I was bowled over by their level of customer care. How nice was that??  So a big shout out to Jessie and Terry at Remco. :D
