Hey guys, so, i replaced my trans, seller used the wrong valve body which resulted in pressure codes for the 2C clutch so i replaced it with my old one and so far so good, but i’ve noticed a few things.
The transmission shifts very soft still, it takes sometimes 3 seconds to complete the 2-4 shift
It still clicks when it shifts into 4th, which sounds like it’s coming from the wheel wells or front of the engine if that makes sense.
Also, both transmissions did something (or atleast this is how the tach showed it) where the rpms climbing aren’t smooth, it’s studdery if that makes sense. Like it jumps around 100 rpm, stays there, jumps another 100, and so on.
The shift flares which are the TCC unlocking are still there, and it all around is pretty much exactly like the transmission i replaced it with, but it has a nice new gray paint on the trans casing.
I ran the codes, and i got a B275B code from AlfaOBD. So i ram a few monitors on the charging voltage, and from what Alfa is saying the truck is requesting 14.1 volts but the battery is charging at 13.0 volts.
I ran an mild alternator test, just by turning all accessories on, and the charging voltage dropped down to 12.4 but then came back up to 12.9 and stayed there. And according to Alfa the voltage is everywhere bouncing from 13.4 to 12.9 regularly, but almost always staying towards the low side of the spectrum.
I’ve had many “Battery Voltage Low” messages pop up in the cluster, and the truck has always had a whine that followed perfectly with engine RPM, that i thought was the old transmission, and that was probably the #1 reason why i replaced it.
Also, the cabin LED lights like to flicker occasionally with the truck running, but they never die out. It usually takes a cycle of the key to get them running right again.
So, the question is, would the alternator cause these trans issues? If so, i’m willing to replace it. I have a picture of it acting up i’ll add to this:
These were taken a while ago with the old transmission, the temps haven’t reached that high since.
