Tranny--not a sexual orientation thread

I have a pair of ZF BW190´s behind two 12v-71 Detroits with Glendining mechanical controls. The port gear is slow to engage/respond, doesn't have the "pop" into gear. Symptoms started suddenly, pressure remains a steady 225 idle/250 under load., temp. oil is clean and topped off. I pulled the heat exchanger to clean/inspect, I don't see anything concerning but would love some feedback what I might look for to ensure the cooler doesn't need replaced. I pulled the gear inspection cover to get a look at internals. All the teeth look great, very minimal metallic from the sludge drains, clutches don't appear burnt, scarred or "out of place". I have a manual so I have followed it to a T, my instinct says the control unit is to blame here, what say ye?

Aren’t glendining controls hydraulic?

I d start by disconnecting the control and engage the gear manually to see if the symptoms go away.

Have you smelled the oil?

How about the filter or the filter screen?

What Pascal said... maybe it's the Glendinning control, although usually their stuff is very reliable.

I haven't pulled the filter screen out but I did remove the two sludge drain plugs and turn the turned it as the manual advises

correct statement--I'll give that a shot

The oil smells well, "like oil" I'm sending off a sample next week

Im with the cable crowd. You might want to check travel on the cable as well. I have the same set up so interested in what you find out
