Hey Gang,
I live in MI and I have noticed this mostly when the car is cold, when I shift form 1st to 2nd before I release the clutch I get a clunk.
Once the car warms up it is not really noticeable.
It happened before and after I changed the transmission fluid.
any ideas?
I have a clunk when I shift between any gear, hot or cold. I thought it was my driveshaft so I replaced it with a 1 piece unit. It did help a little but while I was under the car down at the rearend, I jiggled the pinion back and forth with the driveshaft out. I got about 3/4 inch of play and it made the exact clunking sound. So, could it be excessive backlash as it is in my case? There are a few others here that have had the same it issues and it turned out to be backlash. Unfortunately who ever did my 4.10s really screwed up.
Backlash isnt just from gears. it is also from your u-joints. if you kept the old u-joints from your old shaft, on either end, prob should replace them...
OK,
I figured out the TSB, this is for 2007-2008 mustangs. Mine is an 06 but does the exact thing the TSB talks about.
I just replaced the tranny fluid with synthetic so when they fix it I will lose like 40 bucks.
