Learned alot after reading the fule filter DIY article.
Is there one for changing the tranny fluid? If it is like the old station wagon I had 20 years ago should be a breeze. But do I change the fluid in the converter and if so how?

 

The only way to get it out of the converter on these is to either A - do the fluid exchange with the machine at the shop, B - Do it at home with a $hit load of fluid, or C - Drop the trans and physically remove the converter.

There is no drain plug on these TC's.

Easiest thing to do.....buy the fluid you want, bring it to a shop that does the flush, pay them the labor rate and put in your fluids.

 

I've heard conflicting reports on those trans fluid sucking machines. What's the deal?

 

The only issues that I've ever heard with those things is on older vehicles that the owners haven't ever done a tranny service on. The machine tends to loosen up all the crap that may be crusted on and fixed in a spot and breaks off in larger chunks that can get lodged. On a regularly maintained vehicle, you don't get that buildup, it just flushes out.

 

I like Mayfair have read that those machines can produce to much pressure and damage the tranny some how.

 

I believe as long as the machine stays under 150 npsi you should be OK. If I remeber right the trans builds about 160 psi by itself. (or was that allison?) Got confused on my manufactures, now I don't know.[:@]

 

IIRC there are 2 types of flush machine one uses its own pressure and can cause problems and the other uses the pressure of the transmission to move the fluid. So if you do a flush then use the one that will only use the pressure of the transmission to help preven problems. Also like Jakebrake said if you have not done trans service on a regular bases on your transmission or are not sure the previous owner has done it then I would not take any chances and not use either flush machine I would only do regular filter and fluid replacement changes.

BTW some places who do a trans flush don’t always change the trans filter so make sure the filter is changed before any flush is done to your transmission. So don’t let them try to save you $22.00 ($22. is what it cost me for one from Dodge parts dept. or tell you they are good for up to 90,000 miles) by not changing the filter and run the chance of screwing up a $5,000 transmission
