ZF Transmission on a Hatteras 54

Wow !!!! thanks god I didn't do it yet...I am going to do it tomorrow...

so what should I use then? brake fluid or CRC Brake Cleaner ????

....I was thinking...what kind of debries I am cleanning??? oil ? transmission disc debries? a Carburetor Cleaner would work ??? or a degreasant ...???

Ok I used, brake cleaner and carburator cleaner, and after that I put some compress air and some gun heat (around 400F) to evaporate any water, then I install both filters, and here is the electronic readings:

PORT Trans Press 244 and temp 185 @ 1850 RPM
STAR Trans Press 258 and temp 170 @ 1850 RPM

Same transmission performance before and after cleanning filters...................improvement: None! nada ! Zero!

(was alone...no way to do a mechanic reading jejejejeje)

A guy told me he had same problem....low pressure on a transmission and heating...and it was the transmission oil pump....???

any other ideas (please do not include brake fluid to solution....!!!!) just kidding Capt jejejeje

Hello folks, today I check the Spool Valve for contamination or burrs....and it was pretty clean, I clean it and make a Sea Trial, and I Collect more info: here we go.....any suggestions are welcome ! thanks in advance for all the support

I Measure the increase of temperature (electronic) after reaching cruising speed (1850 rpm's)

At least it is not slipping......!!!!!!!!

Pictures from Sea Trial After Cleanning inlet for Engines

Hello My friends, I clean the seawater inlet from engine, It was very dirty, I take them out clean them and clean the inlet, put them back, run a test, no improvments neither Engine or Transmission Temperature...

There is Something that it is bothering me.....the port transmission pressure is electronically in 240 and manual in 200, I already clean the transmission filters (no improvement).

it is any way to increase the pressure of the transmission?

Strainer Inlet after clean

I cleanned with on-off hull cleanner and remove barnacles....on each individual hole....very...very...! time consumming

But below is the result
