These links have some information on the 4L80E pressure switch. When the gear is put into D1, it should send fluid right to the PMS and that should send a signal to the ECM that it's in D1. So the only way I'm thinking it would read D2 is if the shift linkage is off, which should not be the...

MATCO gauges finally arrived. Just need it to get warm one of these days to run some more testing. Using the EGR sensor helped smooth out the signal a little. When you swapped your 4L80E into your Fbody, did you just leave the PRNDL switch off the 4L80E shift lever and let the PMS tell the ECM...

Yeah the cheap one I have was bouncing and not stable like the videos I watched of others performing pressure checks on the 4L80E so I'm going to get a better mechanical gauge like MAC or OTC. The car does have functioning AC.

I wonder if It would be less noisy just hooking the signal, 5v reference, and the ground wire direct from the OEM EGR harness to the aftermarket transducer and bypass the HP tuners input selector nonsense. Then just do a math transform and point it to the EGR sensor. Stock PCM uses a comparer to...

So how can I adjust the transducer so that the data is smooth and accurate? When I try to use a period of 100ms and "average" function, the values jump up 30-40 PSI over "none" and a period of 0ms. I have my parameters setup exactly as someone that is using an MPVI 2 (100ms and average), using...

Yes, I asked when he has some down time if he could take a look. He is a busy man and I wouldn't have even gotten to this point without his help.

I'm trying to determine if I have actual high pressure or if my transducer is faulty and why there is so much noise in my readings. I'm not sure if what I am seeing is accurate or not. To recap the setup: 2000 Fbody, 2005 core, Jakes D3 Plus, Machined EPC block off plug, line to lube in pump...

Yeah jake said the EPC block off plug works better so I ordered the plug instead after grinding on a brand new EPC per his D3 instructions. Also I just stroked the TCC valve in the pump and the **** coiled pin falls right out as soon as you move the valve. That’s a new discovery for me...

Ok I wasn't sure if there was more to it. I've got my initial shift points set and TCC apply/release tables set. Aren't certain D3 transbrakes fixed line pressure regardless of the power as they have you disconnect the EPC, some grinding the middle land or blocking the EPC completely with a plug?

I'm not familiar with fixed line pressure setups in terms of tuning. The EPC is removed and the bore is plugged, and will probably see 190 PSI but will log it with a 0-4.5v / 0-300psi transducer to be sure. Its a Sonnax LB1 boost valve and LB1 sleeve with a CK purple spring and stock PR valve...

Got it! Thanks for taking the time to explain this.

@clinebarger One thing I forgot to ask you about was the setting of the Forward Hub to Direct Drum end-play to .003"-.008" when rollerzing a stock hub. You had mentioned that if you use a sonnax hub billet hub that comes with the bearing, that the end-play there is zero and is correct. So my...

Took it back down and restacked to pump. New pump bushings are at correct depth and still had to hone these. I wonder if I got fake durabond bushings as these didn’t have part numbers on the bag in the TK-4A kit. Can turn counter with one hand on output, (valve body side facing north) can turn...

Looks like I spoke too soon. So it's got: New sun gear tube with bushings New output shaft bushing New rear case bushing. Granted the bushings were already replaced, but I replaced them again. Stacked to the cs, with intermediate clutches in there and set at .045" with snap ring on int...

So I removed the 34006-SP no walk bushing that was in there and replaced it with a TH400 bushing. I drove it in such that 0.125” was sticking out into the case. Then I put my .030 shim and bearing around it and confirmed that the bushing did not protrude past the bearing. Used Red loctite. Then...

It is weird. I'm aware of all the 95 vs 2004 part differences, but I only have those 2 cases here and wanted to rule out the 04 case as being the issue.

Well it’s not the sun gear tube. The entire 2004 assembly stacked to cs goes in a 95 case and doesn’t bind when rotating output clockwise. Put the 95 assembly in the 2004 case and it doesn’t bind either. Take the 2004 assembly stacked to cs in the 2004 case and replace the output with the 95...

@clinebarger I got one for ya. Well this one is a first, at least for me. Didn't have this issue in previous builds. 2004 late 4L80E case Sonnax no walk bushing inverted, confirmed roller bearing makes contact with output shaft and that the bushing is not impacting rear end play in any way...

Have you changed the shocks/struts yet? I wish KYB made quick struts for all for corners for the 9th gen accords but they don't.

Wanted to circle back around to this topic. It had completely slipped my mind lol. Do you need just the bushing measurements, or also the depth measurements for any bushing that is not mounted flush with the end of the bore? The rear stator bushing goes in .140" deep. The other pump half I don't...
