Muekstar - I'm confused with Step 3 and 4, testing pins 1 and 4. Step 3 says on/off and step 4 PWM. Am I testing the same pins ??? I hope i'm making sense

one more question, You think i would need to remove the solenoid pack to test or can I just test while its still installed

 

Do the PWM test. You have this pack.

The on/off test is for a different unit.

Kind of a pain without an adaptor harness. but you could test in place.

 

Thanks trackspeed

 

I scanned the info from my ATSG rebuild manual.

I bolded (just above the first attachment) the info about using the PWM (pulse width modulated) version of the test in my post. Sorry, I didn't explain that there were two types of TCC application.
It is pretty difficult to access the connection. If you had a pigtail from a donor vehicle, it could be done more easily while installed.

 

Thanks Roland.

I looked for the procedure that was sent to me via email (Company wanted the trans shop to follow strict procedure for warrantee coverage), but it was so many years ago, I guess I didn't save it like I thought I had.

Thanks guys for your help!!! Man i wish I had a donor pigtail so i woulnd't have to drain the ATF and pull the trans pan.

Anyone know where i can buy a pigtail?

Thanks again guys.

 

You can get a new pigtail from Ford for around $40. Ford# 3U2Z-14S411-VCA
Motorcraft# WPT-590
It can also be purchased here. E40D 4R100 transmission wire harness Ford transmission solenoid harness
There are also a few listed on ebay. ford econoline suspension | eBay

 

Roland - Thanks for the tip. Just found one for $42 and they said i can return it after i'm done.

beautiful. Hopefully I can test the ohms without splicing.

 

Can anyone help this Newbie? I tried to check the resistance on a solenoid block that is out of the transmission. The only reading I get is across the thermostat. All the solenoids read 000. Does that mean all my solenoids are shorted out?
