I've been throwing around the idea of hooking up a bypass filter for the tranny between the oil outlet and inlet lines. Do ya'll think it's worth doing?

It would bypass a small amount (about a quart/min) of tranny fluid before the oil coolers to get filtered and then send it back to the tranny. Do you think 1 qt/min. would lead to any tranny overheating issues since it would be bypassing the coolers? Is it possible to pull the tranny lines off and weld or solder a brass port in for the filter? I think that would be the safest way of going about it.

 

You're gonna lose some heat out of the filter and the adapter so I wouldn't think it would hurt.

Just put a brass compression tee in both lines.

 

On second thought. If the filter is more restrictive than the rest of the system, the fluid won't go through the filter.

Also, how did you figure out it would flow 1 quart per minute? If that's the data for an engine bypass filter, then it'll flow a lot less than that since the cooler line is at much lower pressure.

 

I don't think the filter would be more restrictive. Actually the 1 qt/min flow rate is for an 0.016" restrictor orifice on an engine. Not sure if engine oil runs at a higher pressure than the tranny cooler lines or not. That's a rough estimate though. I've heard the tranny cooler lines can reach upwards of 100 psi. That's the reason I'm not too fond of the brass compression tee.

 

bd has a very good filter kit with all components needed

 

I must be really out of the loop. It's hard for me to believe the trans cooler lines can run that high. In the cooler circuits, there are usually hoses slid over nipples w/ hose clamps on 'em. I don't think that's appropriate for that much pressure. Anyway, brass compression fittings are way more reliable than hose and clamps, higher pressure too.

 

True.. 100 does seem kinda high, but that's what some say. Another thing I'm thinking about is welding a port in the factory steel lines.
