Exclamation Need HELP!!! Transmission issue

Hello i am having an issue with my 96 tbird ao let
Me begin with what happened i was driving home from the
Beach and my car started just reving up and not catching
So i had it towed home and figured out that i snaped the
Left cv axle so i fixed it and thought everything was normal
It would go in forward and reverse on jack stands so i take it
Off the stands and go to pull it out of my garage and it goes
Into reverse fine but then wen i put it in drive nothing the car
Just revs up, and idk wat to do i know its no the rear end
Because i took it off wen i replaced the axle and everythings fine
I have also never had an issue with the trans so i dont understand
Why it would just brake idk i it could be a shifter link or what buy any
Ways i could use some help and any advise would help thanks

Edited for punctuation, spelling and grammar so I (and the rest of us) can read it.

Step one - check the tranny fluid, then get back to us.

How many miles? What does the fluid look like? Is the MIL light on or was the O/D light flashing? My 94 lost third gear, but on a rack the car would drive fine, there was enough line pressure to move the tires on a rack but not enough to move them on the ground. I never had a trans issue with my transmission until it finally gave. There are a few possiblities of what could be wrong, a bad MLPS, a burned up transmission harness, or worst case senario your transmission is toast

So, the level is fine? I highly doubt the transmission would be toast after only 66,000 miles.

Put the shifter into manual 2 or manual 1 and see if it changes anything. The MLPS could be at fault.

Ya i dont think there is any line pressure i just
Changed the fluid and there was no metal shavings, the
Drive ahaft wont move in drive only in reverse, this shifter
Linkage looked fine too. How do i check line pressure

Put it into manual 1 or manual 2 and see what happens, and we'll go from there.

Well the forward clutch is most likely not coming on, which will give you no 1, 2 or 3rd gear. This could mean a problem with the shift solenoids, or it could mean the forward clutch is fried. If the transmission had no symptoms prior and failed suddenly, I'm inclined to say the problem is more likely electrical than mechanical. The next step I'd do would be to measure the resistance across the electrical components in the transmission. Pull the passenger side kick panel and disconnect the PCM harness by loosening the 10mm bolt, then do the following tests:

Measure the resistance between pins 27 and 71. You should see 24.5 to 29.5 ohms. Shift solenoid 1
Measure the resistance between pins 11 and 71. You should see 24.5 to 29.5 ohms. Shift solenoid 2
Measure the resistance between pins 51 and 71. You should see 1.1 to 1.7 ohms. Torque converter clutch solenoid
Measure the resistance between pins 81 and 71. You should see 3.3 to 3.9 ohms. Electronic pressure control solenoid


EDIT: Nevermind all that - even with failed electronics the transmission should take off in 2nd gear. If you have NO forward gears, your forward clutch is shot.

First tho, and if it is a solenoid were would i get it and
Are they hard to replace. Thank you very much for your
Help too

The "revving up and not catching" you mention in your first post is the classic sign of a failed forward clutch. Sometimes when they die people report having to rev to 4 or 5k to get the car to move. You also mention it does turn the wheels forward on stands which means the clutch did engage but because it's fried, it has no holding capacity and doesn't transmit enough torque to move the car on the ground.

Sounds like time for a junkyard trans! If you were closer I have a rebuilt one for sale!

I think Brandon got it right on with the forward clutch. I read when you said it was 'engaging on the jack stands but when you took it off it was not' and thought that was really odd. Only 66k miles too; man I would be pissed.


Also why on earth do you type with the 'enter key', a few commas, and no periods...?

That's why the transmission failed then. In stock form, they are not well suited for high power applications because of the massive clutch slippage already happening during shifts. Add some power to the equation and heat and slippage go off the charts. At the very least, the J-mod would have saved your clutches for a few thousand miles.

Darrin @ BC Automotive is in central Indiana and is a well known and respected builder. Perhaps you should get in touch with him about your needs.

You would think if the forward clutch failed, the oil would reflect that failure, but he said it was red & clean!
