I think they're talking about Celsius not Fahrenheit - even in Texas it doesn't get to that ambient temperature ;-)

 

Good read, but the instructions say between 30-50 degrees.

If 50C is 9/5 + 32, then it's 122F, right?

30C is 86F, right?

I guess that 86F is the minimum temp, but the truck MUST be running and at Idle for the fluids to be where they ought to be.......right?

 

There is one thing you can do. Its the thing we do for any transmission while it flares. We do a BG transmission flush. We use the bg fluid and it is the last and only repair before a complete rebuild. The repair can be done at any shop that uses BG products. BGFINDASHOP.COM .. Look it up in your area. The fluid we use for the BG comes in a big box. Its sixteen quarts and works for any tranny. At the same time you can go to any shop that services it. You can even go to another dealership. Shop around for the price. All you need to do is pull the hose off the radiator and tie in with the machine and you are done.

 

Well, that's weird. I got on the BG site and found a guy not 5 miles away. Told him that the tranny began to flare just a day ago, and only from a standing start.

He told me to save my money, that a flush wouldn't help it. Heck, a used tranny will be $2500 for the tranny (not counting R&R) and a build on it will be around $3000, so a build would be the way to go....but am I dreaming to think I can do a backyard flush about 3 times, then change the filter/pan on the third flush and give it a try?

If I do this, should I notice a reduction in flaring after just the first flush (when there's new fluid in the mix)?

 

isn't a flare or hesitation from start? If its a hesitation then you can repgrm the ecu and the tcu together to solve the problem. BTW you are not rebuilding this thing for under 5000 grand. It wont be cheap its a zf. Spend the money do the flush and the reprgm and if it still doing it then get the transmission replaced.

 

Thanks for the vote. I'll try it.

About a re-program, is that something that AutoZone can do with their scanner? If not, a shop with a Snap-On scanner? ...or would it be a trip back to the dealer?

 

If a re-build is going to be closer to $5000 than to $3000, isn't a used tranny like this one worth it if there's a warranty with it? I know it's a gamble, and I know there's labor and shipping involved, but how many ZF trannies fail with less than 30K miles on them?

yes a used transmission is better. And you have to take it to the dealer for the reprogram. ask them to repgm the engine and the transmission ecu together. They charge an hour for the job and thats all you need if you want to do the bg transmission service there then do it if they offer it. do it all in one fail swoop.

 

It's funny that I'm tossing hundred dollar bills around like Johnny Appleseed, but here's the plan for the tranny.

Drain the pan, pull it, and clean/inspect the sludge.
If big chunks of metal aren't lying in the pan, then clean it for re-use during the flushing.
Install new fluid to replace the old.
Run truck for 20 miles, do another fluid change,

Check to see whether the truck is now shifting per OEM.

Is so, get a new filter and do another tranny flush.

If not, get that used tranny and bolt it up.

Any suggestions to the contrary?

 

The fluid will already look brown because of decay. Normal on those. Trust me, you only get two quarts at time and even then it wont fix your problem. Like I said, the BG transmission flush works. it does all fourteen quarts at the same time. You leave nothing in the transmission. The other way takes longer, its messier, you will have issues with low fluid and makes a mess and any fluid lost is expensive and that way doesn't fix flare ups. But hey its your money. I am trying to help you do it the most efficient way. Most of you guys have no problem cutting your nose to spite your face because if you don't do it yourself then no one else can.
