Thanks for your advice and help here on the forum, hzjcm8.
I had my Allison 4 speed back flushed and filled with Transyd at 136,000 miles back in '07 at a bus repair shop that was just getting into RV's. They used a big fancy machine and told me they flushed it until the fluid was the right color, 3-4 times if I remember. At that time they told me there was no need to replace the tranni filters as the back flush would clean them like new.
Is that true?
At 142K miles, I developed a hydraulic leak in the boondocks of Canada. I had a couple quarts of Transyd that I used up along with a couple pints of ATF stop leak I bought as I limped several hundred miles to Prince George. Also added regular ATF as needed along the way (small stores don't usually carry transyd).
Had a leaking hose replaced and the tranni topped off with more transyd. The mechanic told me it was OK to mix the standard ATF, Stop Leak, and the Transyd but I would like to hear that from you.
Should I have it re-flushed, or is it OK with those other fluids in there?
Thanks!
Just a question. Was this a 'hydraulic' leak or a transmission leak. In most cases, there's a difference.
Hmm. I'm not a mechanic but it was tranni fluid leaking from a
hose near the back & under the engine (but not FROM the engine). Three or four feet from the tranni. I think the hose was attached to the rad cooler. I let the mechanic take care of it and he had a devil of a time getting the bad hose out of there because of frozen connections. The only fluid I was loosing on the trip was tranni fluid...which I kept topping off.
It was at the beginning a slow drip I could see under the rear of the RV, just a small 2-3" diameter puddle after each time we stopped (every 4 hours or so).
