Hey guys, I've lurked around here for years researching oil and going on deep dives on the engine and oil side there. Now I'm doing some research on automatic transmissions and fluid because I have my old car back from my brother that is having a transmission issues and I want to get it going again. I've done some drain and refills and just put in a new filter, and, for the most part, it drives fine. What us was doing was not going into drive and left my brother stranded a couple times so he ended up getting a new car. This car has 176k miles on so its definitely got plenty of use for us out of it, but I don't believe its time to junk it. Its too clean and stll runs fine for the most part. I've got it driving pretty good with only the occasional hiccup of not engaging but I can usually get it to engage eventually and then it will drive fine for the most part except for maybe a slight flare sometimes.
My question is this: are there any forums or places where I can find more information on this transmission and the valve body and what eveything does and how it works to get the car moving and changing gears. I know there are plenty of very knowledgeable guys around here and was just looking to pick somebody's brain on this thing from someone who really knows them. It seems like automatic transmissions are like trying to find out how magic tricks work. No one seems to know or isn't talking. Most places just want to replace the tranny (dealership). I can't seem to find much information on these in general. I found some great stuff on Sonnax's website. Sor for instance, upon dropping the pan and poking around I did notice that two of the solenoids seemed to be very loose in their bores. In my mind they should be tighter since they are regulating fluid pressures in the bores and channels in the valve body and whatnot. But in looking at pics of new solenoids they don't seem to have orings or anything, they just slide in and are held with bolt in clips, so maybe thats normal. Long story short I'm not convinced this transmission is trashed, dealer said the forward clutches were gone, but I dont get that when it does engage it drives fine for the most part. Its not engaging and then slipping when you're on the gas. They said it wasn't throwing any codes either. If the transmission is throwing a code the MIL will light right? Or can it have codes stored that aren't a hard fault that can be read like engine codes sometimes?
If anyone can be of any help or point me to somewhere to look online I'd appreciate it.
