Or you could remove the check valve hose assembly and drill the ball out , and pop the hose back on. LOL Of course I cleaned it and blew it out with compressed air. Props for the info btw.

Drill Out Checkvalve
exactly what I did a couple of years ago and never had a problem, I tow a 24' gooseneck with tractor all the time. Don't see why some people make a big job of this, just drill it out.

the check valve is suppose to keep the fluid in the torque converter when the engine is off. but as the plates and clutches in the transmission do their thing they create dust or fine particles and it gets into the check valve and clogs it up and that keeps the fluid from circulating and then the heat builds up in the transmission and then it happens..........................BOOOOOM!! transmission gone.

I'll probably get chided for opening an old post, but I wanted to mention an alternative to the tranny check valve delete that I've worked on over the last few days.
It costs roughly $26 for all the parts at Napa.
(1) Crimp-able Quick-Disconnect Transmission Line Connector (Dodge), Napa P/N: BK 730-4983
(1) Crimp-able Hose End, 3/8" SAE Female Flare, Napa P/N: WH 06U-406
(1) Section of Napa Hydraulic Hose, 8", Napa P/N: WH H24506
(1) 3/8" SAE Male-Male Flare Fitting, Napa P/N: WH 42 X 6
The folks at my local Napa are yahoos, so I didn't trust them crimping the hose ends on there, even though they offer to make hydraulic hoses for you. We have a hydraulic hose crimper at work that worked nicely. The Quick-Disconnect fitting (P/N BK 730-4983) was extremely tight when I pushed it on the hydraulic hose, even before it was crimped down.
Please see the attached photo in the Photobucket link below. I thought it made a neat job of the check-valve delete.
Previously, I had tried to simply cut the check valve off the OEM hose and crimped on the Female 3/8" Flare Hose End (the second P/N listed). This did not work as it leaked transmission fluid from around the edge of the crimp; I think the OEM hose is too flimsy since it is not steel-reinforced. Obviously the double-braided hydraulic hose I used is way-overkill for the pressures this system will see, so perhaps a single-braid hydraulic hose would work as well for this mod.
Anyway, hope this may help someone if you're looking for an alternative to the original mod.
Thanks!
Dave

Getting rid of the check valve has more pros than cons. Several Trans rebuilders do it as part of a normal rebuild, and a few won't even warranty the rebuild unless it is removed.

the shop that rebuilt mine said exactly that. and they cut it out and used new hose with a hose clamp. no overcomplicated "factory look" OCD mod here.... Its a hose people no need to overengineer it if the check valve is removed all those silly fittings can go with it, right?
