I have a 96 12 valve with a 47 RE will shift through all gears when first started up about five minutes and it loses all gears does not try to engage. I have been told torque converter I have one. I can put in it, but I want to see if anyone else has any ideas. The fluid is pink smells a little burnt, but isn’t terrible.

 

Is the transmission full of fluid as measured on the dipstick when warm?

 

yes it is at correct level checked in netrual

 

An easy test with the electronically controlled transmissions is to unplug the connector on the side of the transmission and see if 1,2,3 and reverse can be manually shifted. Overdrive and lock-up won't work obviously.

 

thank you I’ll try it! And if it does have the gears, what would I look into next?

 

Have you plugged in an OBD2 scanner? Getting any stored or pending codes related to the transmission before you unplug the electrical connector on the transmission?

 

If the trans works with the electronics disabled, replace the electronics......

 

no codes at all.

 

Also forgot to mention was have bad tc lock up issue then installed a switch and when you’d engage it then disengage the switch the tc would not unlock and would stall the truck

 

Its rebuild time.
