Love the website folks. Solved a lot of problems by he knowledge here so hopefully I can get some help. I have a 96 f350 with a 460 and E4OD. It is obd2 and I ran it on a computer test at my buddies shop and the TCC solenoid failed. I had a few issues I already fixed like the 3rd brake light and a couple fuses etc but my torque converter still shudders and if im pulling a hill and it downshift it takes a few seconds to lock up. The truck has plenty of power but it feels like its just not putting it to the ground. If I turn the OD off before I get to a hill it will usually lock right up but if its already up and then downshifts it feels like its slipping before it locks. Any ideas? Would a Banks trans-command bypass that solenoid? Thank you folks.

 

If the TCC solenoid is failing, you must replace the solenoid pack. The TCC solenoid controls the locking action of the torque converter directly through directed hydraulic pressure.

Honestly, it sounds like your converter's clutch is worn out, or your torque converter has a crack in the clutch apply piston. Either way, this warrants a converter replacement.

A banks transcommand does not bypass anything but the PCM (engine computer).

 

Ok thank you. So im looking at a new converter and solenoid? Where and how much is the solenoid? I haven't been able to find one. I work next door think Summit Racing (which is dangerous on payday) and they had no clue what I was talking about.

 

How was it determined that the solenoid was actually bad?

 

Would the banks trans-command be a good upgrade after I get the converter and solenoid replaced?

 

The computer test my buddy did showed the test as a fail when it tested the torque converter clutch solenoid

 

OK. Unfortunately you'll have to replace the solenoid pack in the transmission. It's easy to replace but it can be expensive depending on where you get one.

If your solenoid is actually bad, you may not need a converter. Best thing to do would to be to remove the solenoid pack and test the TCC solenoid with 12 VDC.
If it is actually bad, you should replace the pack. If not, you have either a blockage in the TCC hydraulic system, or a cracked converter clutch apply piston.

I don't know much about the banks unit.

 

Wheres the best place to get one? And I've never torn into a transmission any further than a filter change. Any idea the approximate cost?

 

And do you know if a PSD torque converter is the same for a 460?

 

What kind of symptoms would you have with a cracked converter clutch apply piston?

 

First off there may be nothing wrong with the TC or the solenoid pack.

The PCM is electrically connected to the solenoid pack by way of a cable and plugs. The plug at the passenger side of the transmission may have bad wires going into the plug, very common. You need to test the wiring with an ohm meter going to the TCC solenoid while shaking the wiring on the passenger side of the transmission.

If I check pin 4 what should I be getting on the ohm meter? I apologize im not very electrical savvy.

 

I was thinking more of unplugging the PCM computer plug or a plug on the drivers fender and looking for a make and brake ohm reading while shaking the harness to the plug on the passenger side of the transmission.
This plug has been know to have wires come loose going into the plug.

 

Ok ill take a look. When I got the truck everything was covered in red clay mud so I crawled underneath and pressure washed everything. Maybe it just needs some cleaning. The plug you posted is that the plug on the firewall?

 

The plug C1048 I posted plugs into the transmission on the passenger side like in the photo above.
The plug to test with would be C103 pin #9 and any #361 red wire. The 361 wire goes to all fuel injectors and other points originating at the PCM power relay.
C103 is located at the LH side (drivers side) of engine compartment, top of wheel well.
