Advise: Truck driven with broken cooler line

Afternoon all, first post and asking for advise. I recently purchased a RCLB LBZ for a donor drivetrain. The front of truck was wrecked which broke the tranny cooler connection on one side. Pretty much half the line was broken open. I know the truck was driven approximately 1/4 mile after the collision.

Currently the tranny dip stick shows the fluid about 3/8Ē above the very bottom with the truck just sitting there. All I have done is start the truck for a few seconds to confirm it ran.

What can I do to confirm if the tranny was toasted after the collision? Just add fluid and hope for the best? I have a scanner which showed 2 different transmission pressure code. Unfortunately I didnít think to write them down before clearing them to start the truck.

Thank you in advance for any advice.

whats the fluid capacity? if it was only a quarter mile i would check the fluid level, and maybe drop the pan and see if theres any metal in it and how much crud there is.

There wonít be a good way to check without repairing the line. Maybe you did, I didnít catch that. Fluid needs to be checked while the engine is running, preferably with trans temp at operating temp. You obviously canít get the temp up if the truck wonít move, but the dipstick should have a cold hash mark on it. If the truck moves with fluid up to the cold hash, try driving it to get it to shift thru all the gears, as well as trying to feel if the torque converter is locking up. If you can drive it, get the trans fluid up to operating temp and check that the fluid level is at the hot hash mark.

Thanks for the responses. I looped the 2 lines together, forgot to say that. I started it up to see if it would move. It lurched back in R about 1 foot them just revved. Revved in all the other gears. I only ran it for about 30 seconds and now the fluid is about at the very top of the tranny dip stick.

I have no problem pulling the pan of that is the next advisable thing or just add fluid. Just hoping to not put $100 in fluid to find out the tranny is toast. Will probably have to do it though.

It wonít move if itís way low on fluid, and will throw solenoid codes. Sound like you need some more fluid.

Don’t know your exact location but there’s 6 Allison Authorized service centers in the norhern part and over 200 total in California that will have lots of oil or any parts store will have a TES 295 oil also. There’s about 12 TES 295 oils that some one should have locally. I wouldn’t be surprised if you can’t find some within 5 miles of your home.

Thanks for the advice. The closest authorized service center is 25 miles from me per there site. I swung by the local auto parts store and couldnít locate any either.

I can only wrench on the weekends due to long work shifts so ordering online isnít a big deal as it will be on my door before the weekend usually for a better price.

Thanks for the response

Just put Dexron III in it, and do TES295 later.
I can assure you that of Dexron III were detrimental, I wouldn't have 300k mile, untouched, Allisons running around.
