My transmission dipstick for an Allison 740 has a cold mark.  Does that mean cold as in not running or cold as in running but not on the road yet.

Cold as in running but not on the road yet.  After starting the engine, I always place the shift lever in each gear position and then into nuetral before checking tjhe fluid level to be sure all servos, etc. are full of fluid.  Jack

Thanks.  There is so much I don't know.  I had a good chuckle this weekend.  I carry full compliment of spare fluids but I don't know how or where to check or add fluids. 

So I did what every insane newbie does and spent a couple of hours on the world wide waste of time trying to find a picture of the various dipsticks and filler tubes but came up dry.  I then spent an hour with a headlamp and mirror following the various pipes etc.

After the internet search and the physical search I followed with a few hours of quiet contemplation with my favorite beverage.  This lead to one AHA!, the transmission dipstick.  It is atf red.  Haven't figured out where to add yet but first things first.

Wow,

Looks like I sparked some serious discussions on checking fluids and where to check them.

Jack, the fluid does not have a burnt smell. It is also pink as a baby's well you know! My stick also has a cold Hot mark for checking the fluids. I'll probably have to go about ten miles form home before finding that nice flat spot off the road to pull a check on the real level. The road in front of my house is sloped severely from many resurfacings since 1921 when the neighborhood was built.

We are off tomorrow for Long Island NY, stopping to overnight in Carlisle PA. We are really looking forward to this extended vacation.

Thanks for all the helpful suggestions and comments.

Engine oil and trans fluids normally run hotter than engine coolant.

Some trans and engine oil coolers run through the radiator, usually the bottom.

If the radiator coolant wasn't cooler than the oil/fluid it wouldn't cool very well.

Ace,

I will soon be changing my trany oil to Hydrotech and see you mentioned a tranny funnel, When I topped the tranny up the last time(after a hose had broke) I had quite a time and it was awful slow going. Is the tranny funnel anything special if so were would I get one.

Thanks

John,
   Here is a photo of my transmission funnel. Nothing special except the long narrow tube part of the funnel to fit inside the dipstick tube.  You are correct, you will not do a NASCAR pit stop speed fill of the transmission.  Jack
