Thanks for your advice and help here on the forum, hzjcm8.
I had my Allison 4 speed back flushed and filled with Transnyd 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 Transnyd 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 transnyd).
Had a leaking hose replaced and the tranni topped off with more transnyd. The mechanic told me it was OK to mix the standard ATF, Stop Leak, and the Transnyd 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!
Still wondering about this...it was definitely leaking tranni fluid from a tranni cooler hose. Once hose replaced, did not have to top off the tranni fluid level anymore.
