OD light flashing when stopped

[BIGBILL105 45]

I noticed my OD light flashing after I went to the bank threw the atm yesterday. Shut the truck off and continued on my way with no problem. Truck was in drive the whole time with my foot on the brake. This morning, my girlfriend had my truck and brought me my work shoes to the jobsite. I was standing there talking to her and same thing happened. OD light started flashing while truck was in gear and her foot on the brake. Anyone have any idea as to why it would be doing this? I know when the OD light is flashing, the tranny has something wrong either mechanical or electronic. Also, tranny is about 6 months old with about 10k miles on it.

If your OD light is flashing you need to pull the trouble codes for the trans. Usually I find incorrect gear codes. Like 2nd gear incorrect ratio, or shift code like 2nd to 3rd gear shift error.

I planned on that. I'm going to call the guy tonight about stopping over and having him scan it. Really just looking for an idea of what's going on before he scans it. Don't wantall the bad news at once, need warmed up to it lol.

Ok well my experince is once the od light is flashing be prepared for the trans to puke out on you. Which means get ready to fork out money for a rebuild. A good rebuild is from 1500 to 2000 dollars. With your current mods you will want a triple disc converter and good clutch packs.

Notice I how I said trans only has about 10k miles on it. It went kaboom on me before and just had it rebuilt. OD light started flashing and about 50 miles later it was game over lol. I'm going to have my buddy scan it later today and in the mean time, get ahold of the guy who rebuilt it and stop by his place and see what he thinks. What's weird is that it only starts flashing when its been sitting. Trans was at 145 degrees when it flashed this morning.

i know on the older e40d or whatever there code was the blinking light was TC going out of it

Brand new TC in it. I know the light with flash for anything mechanical or electronic. It hasn't done it in a few days, so I don't know what's going on.

i haven't posted in a few months because i have been sorting out issues with my own trans issue but i have to respond to all the hoopla about if the od light is flashing the trans is junk, mine has been flashing occasionally since last july and the truck still goes fine. it may just be an electronic issue like mine that noone seems to be able to figure out.

[BIGBILL105 45]

I know that it can be a mechanical or an electronic issue as you stated. But mine hasn't flashed since saturday morning. Never got around to getting it scanned. Really not too worried about it since everything seems fine. I need to get it scanned though just to see why it did flashed so if it is something electronic, I can fix it.

A long time ago, mine did this occasionally. I think it turned out to be a bad speed sensor.
