need e4od help asap
I have no gears foward or reverse. Everything prior to this was normal, drove and shifted fine, trans temp was 140. I stoped at a store and when I got back in the truck and put it in gear to take off It felt like it went in with a little jump like the engine was reved up, but it was at idle, but still took off normal. Then leaving the lot onto the highway I had nothing? Tried locking in the front, still nothing, seems like the transfer case is in neutral but it still holds in park. It is like there is no line pressure. I have a banks trans command that has been on for almost two years with no problems. the fluid is pink and un-burnt.
Any input would be greatly appreciated, thank you.

Have you had a chance to try again when the transmission is cold?
How many miles are on the transmission?
Is the banks trans command the only mod currently on the transmission?
Were there any drivability problems before this incident (and I do mean ANY)?

three possibilities , #1 cause on that modelis the overdrive planetart hub has split and stripped the splines for the input shaft , 2nd most common is the pump drive gear has failed and is not turning therefore no line pressure and the 3rd most common is the input shaft splines in the torque converter turbine have stripped , this of course is if there is no burnt fluid , you can remove teh pressure tap plug on the left side of the trans and jump the starter solenoid to spin the engine over a few times if the pump is good it will expel fluid if none comes out its the pump failed , after that you have to remove the trans and inspect it further , my money is on the overdrive planetary carrier

A stuck valve could also do it in theory, but usually theres some warning signs before the actual failure.
OEM E4OD torque converters are also not exactly known for their durability either......

it has had some tc chatter in the past but that went away with new fluid and filter. It has 108,000 miles on it. no mods to tranny other than trans command.
If the overdrive planetary went or the tc would I be able to hear a grind or noise of some sort? would there be alot of metal in the pan?
thanks for the replies.

If all that happened was a stripped spline in either the OD carrier or the torque converter, then you may not actualy hear anything over the sound of the diesel.
You will probably find evidence of something in the pan, but you have to look closely, I grenaded the whole overdrive section once and even though the gears were smashed, there was not as much debris as one might expect.
Anything bigger than 1/16th of and inch is to be of consern if its metalic, and has many friends (a single pice may have just come in through the filler tube). You also want to check the pan magnet for larger chunks of steel.

From what I've learned about the E4OD, TC failure is in the top 3, maybe even the #1 cause of failure of the stock 1st gen transmissions.
The trans that I got for my 86 was actually an OEM replacement for one that exploded a TC @ 20 mph while still under waranty.
Your transmission needs to be gutted to see the extent of the damage. I would take everything, and I do mean everything, out and inspect for damage, or shrapnel. Even the smallest piece of metal in the valve body can cause all sorts of problems.
When you get it back together, don't be afraid to spend a little on a new TC, i spent $700 on a billet cover triple clutch. If you ever want more powr out of the diesel, you are going to want as many upgrades as possible.
I'm sorry to say, you are not the first one who has gone through this.

it needs to come apart for inspection and cleaning alright , try to find a dealer for precision of new hampshire they have tough converters that are priced reasonably the one thing you do need to keep the converter alive is a pump modification kit from superior transmission they call it a code 62 kit , this does correct the problem that damages the converter most any aftermarket transmission supply house has them if not you can buy direct search the web for them and you can install the kit yourself
