What, what, what the hell happened??

[Miker]

Are you SURE that it isnt the drive shaft? Mine did the exact same thing last summer. My first thought was the transfer case or transmission.

Drive shaft appears to be fine AND I could not get the front wheel drive to engage, so pretty sure it is not the drive shaft.

Like Viper said, if it will hold in park it isn't anything from the C4 output shaft back. It has to be something in the C4.

If the splines of the output shaft sheared off or the spud shaft on the transfer case went out you would see that problem. Try putting it in gear on blocks and see if you have free rotation of the wheels. Listen at the front of the transfer case adapter for sounds of free metal in there.

I don't live far from Phoenixville if you take it out and want to look inside. It took me two times to get my perfect but I now know a little about C4s. I can't recommend a shop - they are all morons.

Taking them in and out is the tough part. Rebuild parts are $200-$300 plus a converter.

You may not need it so triple check. Take the pan off too and see what good stuff is in there.

340HP shouldn't grenade a C4... maybe a pump or TC?

Yesterday, I along with 2 others pulled a C4 from a running Bronco, replaced burnt clutches and got it back in and running within 6 hours. That included the lunch break and rear main seal replacement.

Yeah but you got trans fluid in your veins. ...

If it was low it would act exactly as you described.

 

[Miker]

If it was low it would act exactly as you described.

What would that mean regarding the probable shape of it?

If it was just low it wouldn't work in any gear. Park would still work. That doesn't explain the big bang but it makes sense to double check the level. It's possible to burn some bushings up like that but it would take a while I think.

Everyone wishes Viperwolf lived near them.;D

No kidding. Having seen him at work, I want to be his next door neighbor. Smart guy!

Takes me 6 hours just to clean the case.

 

[Viperwolf1]

We skipped that part. It was a no budget, got to be fixed today, driveway rebuild.

 

[Ranchtruck]

If you just recently put the motor in Id check the flexplate to torque converter bolts.

Hey, somewhat back looking into this now that it's above sub zero in the garage.

I looked closely at the tranny pan and damn, it kinda' appears to have smooth dimples in front of that teardrop type of recessed area in the middle of the pan. Kind of like rolling dimples where something might have smacked in there half dozen times. I know, easiest thing to do is pull the damn thing and take a look, but what a mess. Its gonna' have to come out so will just do that when it is pulled. I was just wondering if by describing it to you tranny knowledgeable folks whether you have a better educated guess????

If something tried to force it's way out of the pan you have big problems because it would have gone through the valve body first.

Did you ever check the fluid level? If the shop filled it but didn't keep refilling it after the initial run-in (unless you did that part?) then the level could easily have been low as the fluid was pumped through the system after first startup.
