comparison OEM vs aftermarket 3rd & 4th gear pressure switches, solenoids, etc.

so i will be comparing my experiences between using Aftermarket Auto V6 Transmission parts vs. Honda OEM


i finally saved up enough to replace everything with Honda OEM parts

the main components being:

OEM Solenoid A + (gasket)
OEM Solenoid B/C + (gasket) already had OEM
OEM 3rd Gear Pressure Switch
OEM 4th Gear Pressure Switch


my main reason being my 3rd Transmission was shipped directly from Japan and the Transmission Shop also stated they used my old Solenoids? I been getting intermittent blinking D light at high rpms and now recently during cold start ups

nothing like the constant blinking D that doesn't go away but still cause for concern

up until now, aftermarket parts have been ok but replacing Solenoid B/C with aftermarket has caused harsh shifting. I tried 2 different Solenoids and both caused harsh shifting. if you've ever experienced this, it would be like going beyond the crisp shift points to a stutter type shift or harsh shift


weather is finally getting warmer and i wanna do:

3rd & 4th Gear Pressure Switches first

then B/C Solenoid

then A Solenoid


will post results when done.





Pricing

I mainly searched 8-10 Honda Online sites, Hondapartsnow, etc.

Best prices I could find were from Majestic Honda: Total $706.04 in 4/2019

highest combined total went up to $900-1,000/shipped


again, not sure if its because my Used Transmission came straight from Japan and possibly they have different shifting points than US Spec, hopefully this will get rid of the rare blinking D in high RPMs and more recently during cold start shifts








side note: both Solenoids A & B/C came pre-lubed with what i assume is ATF fluid? my aftermarket ones did not and i wouldn't use the aftermarket gaskets or O-rings. for mine, the gasket seemed a lot thinner than Honda OEM and the O-rings weren't a tight fit


hope this helps if your looking for these parts Honda OEM:

How "harsh" are the shifts? Aftermarket solenoid might not be aftermarket, but re-tuned OEM units. The B/C solenoid from Sonnax has the screws at the end turned so that shifts don't glide over but bump over for less clutch pack wear. This is not necessarily a bad thing. All my shifts are way firmer after the rebuild.

"harsh" shift meaning like a normal shift around 2,500 - 3,000 rpm, nothing up top it will shift, but then rpms will dip, then it feels like it engages

i wanted to try a grab a video for anyone who may come across my same situation. i even drove it home and it didn't improve next morning so i swapped it out for the "glide" shifting B/C Solenoid

i had a "crisp" shifting Solenoid for only a short time before 2nd transmission went so i do have a point of reference between "harsh" "glide" "crisp"


will try to post soon when i get back home to CO from work trips

The "slide-bump" symptom seems to be what you are talking about or gear holding a second then shifting into the next gear? That's a problem with the original valve body of the BAYA transmission. This is why I proposed to you to have your original trans rebuilt with the translab shift kit installed, instead of spending $2500 getting a used one installed then another $691 on solenoids. Those new solenoids most likely will not fix the problem you are experiencing.
