Tranny or torque convertor?

[creekfreak]

Got home yesterday from a 1000 mile run hauling a friends blown vanagon home from boise, stepped on it tonite and pop went the tranny....or the convertor? How do i trouble shoot which it may be? If its the entire transmission, is there a better replacement then a stock e40d? What do you rec?
thanks

Whats the symptoms?
Does it move at all? Forward or reverse? Does your od off light flash? Hired your fluid level? Does it smell or look burnt?

They are some replacements out there. Bts had the best one on the market imo. They run almost 5500 for a full rebuild with basically a lifetime warranty.

No movement, OD light is not flashing but have not engaged it, Did not smell anything burning. Ouch, but im guessing its pretty bomber and beefier i need for my stock rig.....thanks for you help.
I wanted to add in after reading a few threads, that, I took off around a corner, certainly hot rodding it a bit as the traffic from the left was leaving the light, stepped on it pretty hard, turbo kicked in and there was just a very subtle "pop" and lost all forward momentum....torque converter?

Could be tc, or could be input shaft

So went over to my friends place where its sitting at, fluid level (cold) looks normal, color is good and doesnt smell burnt. Put it into 4L and was able to get it to move, albiet very slowly. Also with it in gear, pressing the OD Off button, it just stays solid, no blinking. Any other thoughts? Thanks for your time.

Get it to a trans shop for a free diagnosis. I couldn't tell ya what had happened. Its weird that it moves in 4 wheel, but not in two

Could be the out put shaft. Move the truck in 4 wheel and have your friend look to see of the rear drive shaft turns

One more thing, just thought of...lol...

See if the driveshaft is loose in any way at the rear of the trans or at the rear end. Could have broken the pinion on the rear end

Yeah i did check for slop in the drive line, it does have a small amount of movement, nothing major; a 1/4in at the most. Seemed like normal play for a high mileage rig, but i dont really know.....hmmmmm that sounds easy and cheap to fix too! Thanks.

It could be a clogged filter,or the filter has dropped,lowering pressure.Happened too me on my 1st PSD,no go at a stop light,let it cool,limped home and changed filter and fluid.Everything worked fine except I. had some convertor shudder sometimes.Drove it for another 30k before selling.
