Truck Died in Reverse

This is more common when cold weather first hits and doesnt allow any flow. OR you could be like me and have the bypass valve filled up with metal shavings not allowing it to pass through anything.

How do I check if this is the problem? My trans temp was at 95c most of the time today & went up to 115c is this normal?
The truck is stalling alot more now. It's getting worse...

Here is link on how to test it and where its at on your trans. MY advice is drive it and bring it up to temperature crawl under the truck, if the bypass valve is hot, it isnt working. Take it off and inspect it for metal shavings, or it could be just the ball bearing stuck in the seat of the spring that provides the resistance to keep it from opening til it reaches a certain temp.

Thanks Redline, I'll have a look today now I know what to try & where it is.

After reading that link you posted I went out to get the trans up to temp. I only got it upto 85c Then I got a job so had to go do that. It was only a local job for my little bro so I did it. I hope to get time to check it tommorow. I will let you know. I hope it is just that valve.

I'm so busy setting up my centrifuge & it's constantly raining the last couple of days I still havent tested this yet. How much is a new valve dude? I might just buy one anyway & hope for the best.

O yea thanx dude. Thats cheap. I'll see if I can get one here in the uk in a min. The sun has actually come out so I'm going to have a looksee. Let you know what happens.

I took photos, but I forgot the sd card was still in the laptop. I can't get the pics off the camera for some reason. I took the rear end of the pipe off & held a funnel with some hose on it down to a bowl. I got my dad to start the truck in park. Within about 4 seconds the funnel filled. I had to shout to turn the truck off before the atf overflowed the funnel. It was alot of fluid when it was in the bowl so I guess that this is ok. No fluid came out of the rear port. I'm not sure what to do now other than take the truck to an auto transmission place. I do know of one in London that deal with American trans, but most garages here don't know what my truck is. I do everything myself normaly.
The truck is that bad now that sometimes you have to put it into neutrel before you stop before it stalls. Everytime you select reverse it stalls or it will take off backwards at about 100mph.

How much do you estimate was pumped out, 32 oz's? in how much time? (15 seconds or less?)

If its the proper flow which it sounds like i would DEFINITELY look at the torque converter as the problem, and 9 times out of ten when the TC goes it fills the trans with garbage and takes it down with it. Its locking up every time you put it in gear, my trans did the EXACT same thing. Im betting you need a new trans, and some more advice, do NOT get a re-manuafatured one.

BTS sells/ships everywhere, when I was at their shop they had pictures up of companies and their trucks in Australia they sold/shipped transmissions to.

Good luck, and it sucks to have a trans go out..ive had 4 of em go on mine in 173K
