95 auto transmission issue

[rubydist]

so if it only shifts twice, there will be codes - let us know what they are.

Ya know as someown who owns 3 other mustangs and I do all the work with the help of friends ourselves including superchargers nitrous turbos cams intakes entire engine swaps! And do electronics and electrical work, This was pretty confusing but I think and hope I got it; appears as if there's 3 codes... 172, 332, 648

Just looked them up first is an o2 sensor error, 2nd is a egr error 3rd is you guessed it 4th gear failure!

If that doesn't work you don't have a properly functioning trans....

When my original unit crapped out I lost 3rd gear, didn't get it back untill after the rebuild.

Was sooo happy to pull apart and find exactly as described as above, broken c clip and all, I replaced the whole thing with the one out of the other trans only to take it down the road and have it do the same damn thing!!!! Tried resetting the computer and tried again that changed nothing.

 

[rubydist]

I'm guessing that while the clip was in the process of failing, it let the servo only partially engage long enough that the clutch/band now just slips. It will need to be rebuilt to work properly, unfortunately.

So while doing fluid checks on the car I added maybe a 1/4 quart of trans fluid yesterday morning, drove the car all day including a 45 min trip each way to a new years party, this morning went to breakfest, od is currently working... wtf?!?!?!

 

[blown86gt]

Okay so it worked all day till I made that post, and it shifted the 1-2 shift perfect without the jolt it had been doing....does this lead back to the vss maybe? Or possible a filter/fluid change? It shouldn't be the trans, possible the od soilnoid it self?

VSS - Vehicle Speed Sensor
TSS - Turbine Speed Sensor

Could be an internal selonoid which can be done by you if you wish. Behind the side trans pan is where you will find them and they are not very expensive.

Like I said it would be best to just change the VSS to rule it out. It's under $30 and is relatively easy but annoying to change. I have had no VSS codes before and had success in changing it to solve intermitant problems. If your having issues with 1-2 upshifting and 2-1 downshifting it can usually be related to either internal clutch issues or TSS (not VSS) issues.
