Three more fuses to check. These are for the transmission and shifter, not the TC system. See figure 04.1 In the wiring diagrams, previously linked.

In the primary junction box (inside the cabin), check F15.

Under the hood, check F33.

In the trunk, check F3.

 

Just got out form underneath the car.
Megtronic connector in and tight.
Checked F15,F33 and F3. All 3 good.
Also checked fluid. It was clean and full
Anything else I can check?

 

How do you know its "full"?

 

When I pulled the fill pug underneath fluid came out all over my hand.
Put the pug right back in and tighten it.
I would think that would be enough fluid to engage at least.

 

Possibly not.

Undoing that fill plug when the engine is not running means that any fluid pumping around all the internal parts, which is several litres at least, is now settled out mostly.

If no fluid runs out when the engine is running at between 40-50 deg C , with car level, then the fluid could easily be low.

 

I understand.
I'm skeptical that its fluid related due to the fact the car was diving fine before this.
I would think that it was fluid related it would have happened slowly with slipping over time.
This happened all at once after getting on it a little to hard.
I have a feeling its just going to have to go to the shop.
I don't have everything I need to troubleshoot this problem and my knowledge on this jag is limited.
If it was a Chevy, Regular Ford or a Dodge I probably have it figure out by now.

 

Vast numbers of cars use the same trans so if you could figure it for those others why not this one? It's just an autobox so if you know others what's the issue?

As I recall, they all hate the wrong fluid or low fluid and can all suffer worn parts.

 

Without DTCs we are guessing.

I 'guess' you should replace parts until the problem goes away?

 

I have a truck in route to take it to a transmission shop that was recommended The Jag Shop.
Will let you know what I find out.
The mechanic at the Jag shop and the transmission shop both said it was strange that it wont try to move in any gear and no noise..
They both believe its something internal.

 

Fingers crossed for an easy fix...

Sorry we don’t really have much of anything else specific to suggest. You’re definitely in uncharted territory here. It’s not like the other recent transmission thread where the symptoms quickly pointed to loose mounting bolts for the shift cable, a known and common problem.

Please keep us posted with what the shop finds.

 

Any word from the transmission shop?

 

Talked with the owner Friday evening.
He had not had time to put it on the rack yet but went out and rant it thew the gears.
He said the same thing I told him. Wants to engage but doesn't.
Hes going to put it on the rack and check the fluid Monday and run some tests.
If it full Hes going to pull the pan and check and see if he sees any pieces floating around.
We also spoke about a possibility of the valve body seal.
Hes about 95% its going to have to come out for disassembly to find the problem.
He told me he has a feeling its a broken input shaft. Not what I wanted to hear.

 

Once you drain more fluid or drop the filter pan your window of opportunity to review real time what is going on with the transmission controller and check for codes via the OBD link will be passed. Not to throw shade on anyone's process but that really should be the first thing done. Once the fluid is out, new fluid will need to go back in. You won't want to waste much of that fluid, it's pretty expensive. And the pan is the filter, you won't want to reuse that either.

 

+1 on the above and I have never seen a broken input shaft mentioned before.

Not in this forum or on the many you tube videos of rebuilding these transmissions I have watched.

 

I'm bad he said diagnostics tests.
I'm fairly sure hes going to read the codes prior to doing anything else
Hes got a lot of work. I'm sure he wants it out as fast as he can
The owner at the jag shop said hes been doing transmission rebuilds for him over 25 years.
Advanced Transmission & Gear 4.8 star rating out of 5.

 

Yikes

I hope that's not it. Seems you'd have heard a horrendous sound if the shaft snapped.

Isn't the oil pump driven by the input shaft? If there's a fitting to connect a test gauge, that should give you an idea if the shaft is still intact.

 

I think the front pump is driven by the snout on the torque converter.
The 2 flat spots that fall into the pump.
Your right, you would think you would of hear one hell of a bang if it broke.
I think we are just grasping at straws until he gets it up on a rack.
I will update when I find out more tomorrow.

 

Update:
Just got a call from the transmission shop.
Input shaft broke off clean at the the drum.
I believe the way he was describing it was actually the drum spline that broke or around it..
Needs a new input shaft and drum. Also front pump and some miscellaneous part that I didn't pay attention to.
1900 total to repair.
Guess that's better than 4000 for a total rebuild. Till hurts.

 

Wow, the guy sure called that one, didn't he? I thought he was out in left field...

I can safely say I've never heard of that failure before. Is this a known issue with this transmission? Just curious, did he scan for codes? This could be very helpful for the next guy reporting similar symptoms. It would all depend if the computer is even programmed to monitor for such a condition, perhaps by comparing engine RPM and some parameter from the transmission. Some scenarios are so unlikely, they aren't even monitored.

Sorry to hear the fix is so spendy.

 

Never heard of it before. Rarer than rare.
