Is there a waiting period between when you get the flash done and when you can start towing again? I was thinking about getting the flash done Thursday, but am leaving on a trip towing the camper on Friday. Wasn't sure if it is one of those deals where you get it done and can't tow for 500-1000 miles. If so, I can live without the flash on my trip because it doesn't seem to have any harsh shifts in trailer/tow mode.

 

I got the 6.2 flash done with no special instructions - the next day - maybe 50 miles later I was pulling 12k cattle/gn trailer for about 150 miles and have had no ill effects..

I told shop foreman I was going to do it - & he didn't mention anything...

Also, right before I hooked to trailer, I checked the trans fluid because on the gasser they had to drop the pan & put some solenoids in there relating to the flash..

Only thing I saw was they had not fully seated the dipstick but level was fine..

 

I was just thinking that this will reset the transmission learning process and I didn't want to skew that with trailer towing.
