If non synthetic transmission oil, look and sniff the transmission dip stick at around 30,000 intervals.* If the oil is Mercon V, semi synthetic, you can run it longer. When the car shudders on a slight acceleration up a slight grade, change it.
Remember to also change the oil in the torque converter and filter in the transmission.
*Discern the quality of the oil by detecting whether or not it is "burned" = Sniff test. The color should be close to when it was new. When it smells and looks bad, change it.
The car belongs to a friend of mine but I believe it's an '85. I don't know if he's changed the oil previous to this. It's still running good though. It is amazing to me that after so many miles - it should be over 100K - this Mustang has required minor repairs. It'll be nice to compare this tranny to the one with the electronic controls introduced in '91.
I just purchased a 2005 V6 Mustang coupe. 44k miles and in AAAAA1 condition. I spent $2000 changing this and that under the hood, plus new tires. Lots of things replaced that probably did NOT need to. However, I am 72 and try very hard to avoid highway breakdowns. There is NO dip-stick and I need to know when I should drain & refill new tranny oil. I gave some online service a $5 donation to answer that and never got a reply. Also, I find every aftermarket company that sells interior chrome trim to be total thieves as to what they charge. $70, $80 $90 for shinny covers to put on the radio buttons????? Nuts!!! If you know when I should change the tranny oil, I would greatly appreciate a reply on line. Thank you.
I have a 86 f150 4x4 with an aod trans I purchased a used trans and it wont shift into R or N only drive even in R ort N seems to be stuck in drive even thogh ithe shifter moves. any one out there that can help me?
