Blowing tranny fluid all over.

Scott & Heather · June 04, 2018, 11:34:09 AM

Well I removed the hose and I'm having Pirtek make me a new one. I'll probably just be buying normal fluid at this point. I should have taken cliffs advice last year and not put transynd in

Hopefully you didn't damage it with the fluid low.
Lol using synthetic oil and changing it every 3 to 5 thousand miles.....I use it in my 03 Jetta tdi and change every 10,000 miles. Odometer is 254,982. Runs great, never needed to add oil between changes.

Just out of curiosity, what is the typical pressure in the coolant lines of a transmission? I have an MT 647, I imagine a HT 740 would be similar. And that made me wonder if the temperature recommendations are in the coolant out line, before the transmission cooler, or in the coolant in line after the cooler

I'm about 200,000 ahead of you (459,000). Never put anything in but Mobil 5W-40 pure synthetic. I run 10 - 12K per oil change. Put in a new timing belt last week - you can still see the original machining marks on the cam lobes. It's pure amazing.

I have 2002 Chevy pickup 5.7 with 282,000 miles lol it never had anything but what the oil change places put in it every 6000 miles, and on sale of course I won't pay over 20 bucks for a oil change , it has had every brand even W/M in the engine and it still doesn't use any oil and gets 21 mpg. I drive it just to see how long it is going to last lol plus it will never happen me paying 60 to 80k for a pickup

Had Prevost Service Center Put Transynd in mine (755CR) and they said 100,000 change intervals.

So to reiterate, can I refill with Dex iii? New hose arrives tomorrow morning so I need to purchase at least 5 gallons of fluid.

I would. If it turns out transmission was damaged moving it low on fluid, all of will be dumped if it needs pulled and repaired. You can change it more often and save on the cost of the fluid.

Thanks so much... here's to not having toasted my trans. If I did, I think I'm going to swap
In an HT740. I'm already sick of this electronic ATEC garbage.

I doubt you hurt the transmission if you only take 5 gals it probably went to the limp mode to protect it anyways

What condition is the other hose in???

Yes, you can mix, just follow the lesser correct chart for replacement.

With a "proper" leak like that, I expect the tranny stopped working right, before you could wreck it.

Fill 'r up and down the road.

Happy coaching!

I was reading the part that it didn't want to go the last mile. I envisioned it slipping to keeping it moving. That hose that leaked....had it been rubbed or hit by something in your travels, or was it just a hose failure?

So, to answer some posted questions.

I replaced the hose today. Cost $182. Added 4 gallons of fluid and it's now above the lower line of the "hot". Coach seems to drive absolutely fine. Have no idea what will happen 10,000 miles from now but it's ok at this point.

Basically we were a mile from our destination when I went to take off at a stoplight and the coach was kind of lethargic but it did take off and reached normal cruising speed. Then when I pulled into the parking lot I noticed there was fluid all over my truck in the back of my boss and it was dripping fluid out of the pan. At that point it was really hard to get it going and I just basically pulled into my parking spot.

Other hose is fine for now. Hose wore through at a retaining clamp. Silly design. I removed the clamp.

New hose is pretty:
