I've been having troubles with my automatic transmission for sometime now mainly it's lost it's smoothness and has been slipping first thing in the morning. I've practically worked on every other component of a car but never ventured into or near a transmission so I don't know where to start. Basically, I shifted into reverse as usual the other day and recently whenever I've shifted into reverse its been a rather rough engagement but this time there was a more decent thud and now reverse is just another neutral gear.
All my other gears work as expected, except it's now more rough going into drive sort of like how reverse was engaging for a while before it finally failed, which is concerning.
- -Have only owned the car for a few months
- -Haven't changed the trans fluid or filter or any of that, fluid looks a little light brown but is at the correct level
- -Right hand outer CV seems to be knocking too
Haven't had any time or place to raise her up and take a look at it all properly but I do notice some fluid on the left hand CV that I can see from above. I've also noticed that it seems to smoke almost twice as much in reverse as it does in drive (usually only when I first start it up on these cold mornings).
I read somewhere that an item called a "vacuum modulator" can fail and suck trans fluid into the inlet manifold and cause the car to smoke white which is what it does in reverse, but as I say transmissions are not anything I've looked at before so I can't confirm or deny that. I'm planning to have a proper look on Sunday, if any photos would help please let me know and I'll take some.
I also have a rebuild manual for the transmission and all other related components I grabbed so that should hopefully help too with any advice.
