trans concerns with flush over fluid exchange
So those of you that I talk to on the box know I'm headed from the Mexico border to Washington.
Like the good Marine I am I'm prepping my rig for the journey.
I have two concerns.. one is changing the fluid in the trans and doing the filters. While some say to do a flush and filters, I am deathly afraid of doing flushes... had a bad experience where the flush made my old Chevy trucks trans loose gears...
This close to making a journey that is one thing I cannot afford...
So should I play it safe and just do a drain?

There have been two very long threads on this subject in the last few months. My opinion is the flush is the way to go, however you may have a hard time finding a shop with a HOT flush machine. It's necessary to preheat the fresh fluid going in to keep the thermostat in the trans open. If it closes during the flush you wil be dumping your fresh fluid and old fluid will be trapped in the trans.
A few options were posted from preheating the fluid in the oven or a gas fish cooker to blowing compressed air through the cooler and lines to get more fluid out but they seem like a lot of effort for little return or downright dangerous.
Another option many seemed to like was to install an newer model trans pan and filter. Better filtering and a bit more fluid capacity.
I think in the absence of a hot flush machine, dropping 9ish quarts and replacing the inline filter can keep you trans working fine but it's important to keep an eye on the condition of the fluid as well as level. Any darkening that could indicate the fluid has been overheated should be flushed reguardless of where your at on your schedule.

I'll look into the newer pan.
