Overdrive OFF light flashing question
Hi all, haven't been on this forum for a while.... actually found a JOB!! after 5 months. Part of the job involves towing a trailer with a pretty large load. I just completed a 12 hour trip from Hailey, Idaho to Sand Point, Idaho pulling a 26 foot trailer with a full load of cabinets. I was real careful to turn off overdrive over the two mountain passes and had no problems during the trip. The last leg of the trip was an extreme uphill from Sand Point to the Schwietzer ski area, real slow, many hair pins, burned about a 1/4 tank of fuel in 1/2 hour. Even though I turned the overdrive on the shift lever to "OFF" it started to blink. What does this mean, should I do something to prevent this? This long hauling is not something I'll have to do a lot so would prefer to not spend much on some expensive mod. Thanks in advance!

A flashing OD light usually means there is a tranny code set. Have the codes read. If there are any be sure to post them.
Be sure to clear any codes that may be set so you see if they come back if you get another flashing OD light.
It may be a code set due to overheatig that once cleared may not come back. If you are going to be doing any more heavy towing flush and fill the tranny if it has been awhile. I know you don't want to spend money on mods but a tranny temp gauge and auxillary tranny cooler could save you there cost from preventing any overheating.
Congrats on finding work.

Brian eveything else is ok Robin sorry- sitting on top of a mountain so no way to read codes. After we unloaded for about an hour it stopped flashing, so it's probably ok but I'm concerned about what to do on future hauls. Don't want to be stranded out in the middle of BFE with no tranny.Thanks for the replies.

Also check your ATF. Does it smell burnt or is it discolored, very dark?

EGT gauge also suggested.
The number one killer of transmissions is heat.

Thanks Robin,
The fan didn't seem to be kicking in any more than normal (had a Chev 350 that did that a lot) Really just wondererd what the flashing OFF light meant. It's pretty cold around here so i doubt the engine temp got that high, but not sure. Thanks for the input, just drove 12 hours and unloaded for an hour so am going to sign off Talk to you soon
