Pulled the top pressure sensor out. Broke and the plug also broke with the wire. Gonna replace it and the other sensor aswell next
Ok well if you're going to rebuild that transmission I have 29 videos, 15 hours worth of me tearing it down and rebuilding it from the ground up including the "root causes and fixes" if you will. it's on youtube under the account eksine. there is a how to remove the transmission. you're theories while , it appears that way to you isn't quite on point. the transmission does have a main filter in it, also should have a bypass hole so if it is clogged it bypassed that clog, unfiltered. there is a secondary external canister filter under the battery tray, that also should have a bypass, all assuming these are oem parts, if aftermarket than probably no. the dual solenoid on top has a plastic "adjustment screw" it is shaped in a pentagon. clockwise or counterclockwise adjustments will change your hydraulic pressure in the transmission. Don't mess with it if you have no idea what you're doing. that is only if your transmission is only slightly out of adjustment, since you have catastrophic pressure loss, your problem is elsewhere. the second problem you have is that a pressure loss, which is your theory for right now, means either the main gear inside the main valve body is leaking fluid because it's chipped a tooth or worn down, whatever. this would cause an overall pressure loss. another reason would be that due to a full filter, all debris has worn down the valves over time and it causes leaks around those valves. you could fix that by buying oversized valves, but likely it means getting another transmission to start on a known good core. another theory that you haven't thought of is if it's an electronic malfunction. the ECU serves double duty as the engine control unit as well as the transmission control unit. to reset it unplug the battery and let it sit for a while. a few days if possible, than reconnect and see if the ECU is reset. if that still doesn't fix it it's still possible the ECU is bad there is actually a way to test your low pressure theory. the left end cover on that transmission has 10mm bolts that are acting as caps for the moment. it's designed for a technician/ engineer to test the pressure, there's several bolts with washers. I have no clue what each one is or how to test it, but that's how you do it. the only way to even get a clue about what's going on is to open up that transmission. but like I said, the filter isn't the problem it's somewhere else. also like I mentioned watch those 29 videos, plus the other one, you'll get a better idea as to what I'm saying
Pressure would be the same at the switch as at the test port. However, they are different parts. Each test port is sealed by a bolt with an aluminum washer.Those pressure test ports would be the two switches I ordered?
