Well, sounds worse than I expected. But all may not be lost just yet. When you loosened it the first time did you tighten it back up? Really tight or loose? When you were on the way to get the torque wrench did it make any weird sounds? can you describe exactly when the problem first happened and how long you were driving prior to that and if it was driving oddly before the prob happened?
Also, why were you adjusting the bands in the first place? Are you sure that the linkage is hooked up right (probably is). Are you also sure that there is enough fluid? Have you tried to leave it in gear for about a minute to see if it would engage (don't rev the engine when doing this) if not try R first then try D wait a bit.
I think that is all of the questions my mind can come up with right now.

How did you adjust the bands? What exactly did you do? Any strange noises before she died? What did the fluid look before the failure, then after? Why did you think you needed to adjust the bands in the first place?

Required tools for operating a Vintage Mustang:
1. Duct Tape
2. J.B. Weld
3. B.F.H. (Big Fat Hammer)
4. VINTAGE MUSTANG FORUMS II

I came to your predicament a bit late...

My understanding is that your problems started after aborting an intermediate band adjustment because of a defective torque wrench and then driving the same vehicle to get a new one....is this right?

When you went off to get the new wrench, tell me exactly where you left in the adjustment process...

BTW, a moderate pull on the appropriate size normal end wrench will give you approximately the torque you need...I've never used a torque wrench to adjust bands in all my years of mechanicing...

If you left your band too tight, you might have burned the thing up...how does your fluid smell now? and appear? Compare it to the smell and color of some fresh fluid out of a can...

Do I understand correctly that you can't engage any forward gears or reverse? Tell me about any other work you did to the car prior to attempting to adjust the bands....and, did you succesfully adjust the low-reverse band? If so, explain the exact procedure you followed...

That's all for now....let's take it one step at a time and not drive the car anymore until it's right (even if it does move)

ok...the reverse band i did not mess with at all..
the reason why i tried the adjustment with the intermmediate
was cause she was slipping a bit...
from 2nd to 3rd..
before i left to get a torq=ue wrench i gestimated about where she should be set...
when i got on the freewAay....she seem to be holding back..i was giving gas but no speed increase...above 45...
or 50...so thats when i pulled over and there was no gear to shift in..
i will check the fluid tommorrow morning as it is real late now.. but i did notice a burning smell when i pulled off the main road..
but like i said..,.i got under her and you can move the shift back and forth by hand..almost no resistance...at all...and
she is leaking fluidright where the nuetral switch is[where the gearshift is bolted to]....
how bad off is it?
i get nauseous every time i think about it..
she starts up fine..its just that there is no shift...at all...

My guess at this point is that you didn't back off the band adjustment enough and burnt up the intermediate band and/or drum. There are seals inside the drum for clutch actuation (I'll take a look at my schematics today for some particulars) and if things got hot enough, may have cooked them, causing a loss in hydraulic pressure to actuate the clutch pack....

Normally, I give the intermediate band adjuster (with locknut loose) a moderate pull with a short (4") handled end wrench, then back it off 1.5 turns and then, while holding the adjuster, tighten the locknut.

How does this compare to what you did....?

BTW, I also had a sluggish 2-3 shift when I bought my D-coder back in '93 but the installation of a shift kit cleaned that right up...the trans now has 199.4K on it and shifts like new....shift kits are worth every nickel...I did adjust the bands when I installed the kit but they were right within spec...C4's are a durable tranny if maintained...

You may have to punt on this one....scrounge up 400-600.00 and get a rebuilt tranny and converter....

Try posting a new inquiry once you have more info and reference the previous three threads in your post....some of the gang who know this stuff may have been away as I have been...

Good luck!!
