Water Pressure 98 Alpine 36MDSS

1. Water pressure. If I connect city water directly to the fresh water inlet (no filter), I find that over time the water pressure inside the coach has gradually reduced, and now is almost a trickle. When I de-winterized this spring, it took nearly an hour to fill the HW heater, and all faucets have very low flow for both hot and cold. No obvious leaks, just very low flow. Is there maybe an internal filter somewhere accessible that might be clogged? Or is it a known issue with an available fix?

2. The Allison shifter has lighted readouts of current and target gear numbers. Over time the brightness has diminished so much that while driving in daylight, reading the gear numbers is basically impossible. Sometimes this gets scary, like when needing to downshift to slow on a downgrade or coming up to an intersection. It there a known fix or replacement for this issue?

Item #1
City Water Inlet connection has a screened washer taht can get clogged
City Water Inlet Assembly has an Internal Check Valve that can get cockeyed, O-ring dislodged causing diminished flow/pressure

No OEM filters but PO might have added one. Does low flow affect both hot and cold water output? Does the flow improve when on the fresh water pump? If so, issue is at the aforementioned inlet point.
PS--your post suggests you fill the water heater with anti-freeze? Or did you use the by-pass valves and just drain the heater?
PSS--transmissioninstruments.com repairs older model keypads and may have extras for sale? A new pad from Allison will be expensive, if even available?

For Allison shift pad question, try turning the dash lights to high.


If that doesn't do it, contact John: https://www.transmissioninstruments.com/
