<_< Has anyone heard of a torque converter going bad in the Bronco's? My OD light on my shifter will blink on and off after about 15 or 20 minutes of driving time. Last time it did this the dealer said it was the torque converter $500.00 later it is find. Well that was at 80,000 mi now were at 165,000 mi and it just started doing it again. Any one else have this crappy problem?

yes, i have. as a matter of fact, im finishing repairs this weekend (we gotta mount the tranny). it sucks, do it in a garage, with a lift, or better yet, if you have the funds, get someone else to do it. should only take 2 days or so.....
Does it shift hard? if so:
The flashing OD light is an indication of a transmission related trouble code stored in the Powertrain Control Module (PCM). When it has a trouble code related to the transmission it usually commands full line pressure to try to protect the transmission from damage. Normally this is caused by a transmission slip code. Have your computer scanned or diy to see what transmission codes are stored. If it is a torque converter slip code keep in mind it could be stored from converter clutch slippage, or slippage in another transmission clutch pack.

also. somethAng that happened in my 96 E4OD;
The bulb /switch at the end of the shifter is flaky. The wire that connects the Transmission Control Indicator Lamp (TCIL) (OD switch/light) at the end of the shifter is being worn at the column.
Codes to the computer and the light flashing in a "repetetive pattern" and consistent manner indicate a trani malfunction. A flashing OD light that is sporatic, has no pattern, is accompanied by sporatic OD engagement indicated that the wires are being worn and possibly shorted at the steering column below dash. The light flashing in a sporatic and sometimes on and sometimes off for longer periods indicates a bad switch at the end of the column.Ford sells new LED/switch for about $12; O/D LED/Cancel Switch Part #F58Z-7G550-A

ISSUE:
Some vehicles may exhibit a flashing Transmission Control Indicator Lamp (TCIL) and Diagnostic Trouble Codes (DTCs) 62, 628, and/or 1728 may be stored in memory. These DTCs can be set by any internal transmission element slippage or potentially by torque converter slippage.
ACTION:
Refer to the following text when servicing these codes.
NOTE:
WHEN SERVICING A VEHICLE WITH A FLASHING TCIL WITH DTCS 62, 628 AND/OR 1728, DO NOT REPLACE THE TORQUE CONVERTER UNLESS PROPER DIAGNOSIS HAS PROVEN THE TORQUE CONVERTER TO BE THE CAUSE.
Always verify the customer concern. Proper diagnosis for DTCs 62, 628 and/or 1728 may require talking to the customer to find out if there were any other symptoms associated with the TCIL flashing, (i.e., shift concerns, erratic/early/late, proper torque converter operation, etc.), prior to noticing the TCIL flashing.
Prior to transmission repairs for DTCs 62, 628 and/or 1728 or investigating other causes, repair all non-related transmission DTCs first, then repair all other transmission DTCs other than 62, 628 and/or 1728.
Some of the other causes that may result in DTCs 62, 628 and/or 1728 are as follows:
- Aftermarket modifications (i.e., performance enhancers, electrical modifications, etc.)
- Missing shifts (some/all)
- Transmission fluid leakage (internal and/or external)
- Erratic shift timing
- Valves, springs or retainers in the main control/accumulator body not assembled correctly, binding or sticking
- Check balls missing and/or mislocated. Damaged, unable to seal/seat properly
- Higher or lower than normal line pressure
- Transmission fluid restrictions and/or level
- Erratic/inoperative vehicle speed and/or rpm sensor
- Poor engine performance concerns
Any vehicle system concerns that could cause the strategy to detect a perceived internal slippage or change in the expected rpm of internal transmission rotating components may cause DTCs 62, 628 and/or 1728 to set.
NOTE:
ONCE DTCs 62, 628 AND/OR 1728 SET, OTHER TRANSMISSION FUNCTIONAL DTCs MAY NOT SET.
