I created this diagram to keep my marbles straight. I think this is the same way I had the other cooler plumbed, but after I removed it I can't remember how it was done. From all my research, this is the correct way, but I want to have my sanity checked. Things that I have found contradicting information on, and sometimes in the same thread is the correct outlet for fluid out of the transmission.
If it looks good to you let me know. If I can improve this drawing let me know. I plan to also illustrate it further with the exact fittings I used at each turn and junction, so that someone later will have an easier task of procuring and assembling the parts required. ORIGINAL DIAGRAM REMOVED TO AVOID CONFUSION --- SEE CORRECTED DIAGRAM BELOW |

Don, I haven't had a chance to check the routing in/out yet. But my question is why would you want the return line so long? Is it due to engine compartment configuration? Just the diagram? I would want it as short as possible, not sure if the cooler is one way only and/or if you could switch cooler inlet/outlet?

Drawing is not to scale and I didn't want to cross the lines on the drawing for clarity. When it comes time to do a final photo diagram of how it was plumbed I'll take actual photos of the routing and fittings installed. B&M says when mounting the cooler on its side to make sure the inlet is on the bottom with the top fitting returning fluid back to the transmission. Should avoid at all costs pointing the fittings down as this can cause air pockets and poor cooling efficiency. Good Question |

Why would it make any difference?

Andy - it probably wouldn't make any difference, but saves on expensive braided hose... LOL |

I'm gonna bump this up on the list for another day or two while you Gurus think about it... LOL
If you have any comments I'm open to suggestions before I put the final hose routings together. |

Hey just saw this. It looks like you have the flow reversed on the trans but good elsewhere.
Bottom trans fitting is output flow to the bottom of the radiator cooler, top of radiator cooler to the bottom of the aux cooler. Top of the aux cooler to the top of the trans. |

Welcome! I saved the pic. I did some testing as I've gone through several trans configs. I had it not going through the radiator for awhile. It only ran slightly cooler and would get extremely hot in traffic. I didn't have a fan on the cooler though.

Andrew, where did you put the pickup/sender for your trans temp gauge?

Don, I'm not 100% but doesn't the fluid flow out of the trans and into the top of the radiator cooler then out the bottom of the radiator cooler? I don't have my fsm with me.

Yes stock is routed that way. When I redid the system on mine I followed the tips at B&M. http://bmracing.com/bmracing/images/bm_cooler_techdoc.pdf Mount the B&M SuperCooler with the fittings on top or on the sides. It is not recommended to mount the cooler with the fittings pointing down as this may create an air pocket in the cooler resulting in reduced cooling efficiency. *** When mounting the cooler with the fittings on the right or left side, the lower fitting must be the inlet with the top fitting routing the fluid back to the transmission. *** |

Not long after I got the car I installed one in the pan. I changed the fluid and filter then used the typical drain plug kit. Pic for location reference: [IMG]http://i119.photobucket.com/albums/o130/Aardwolfki/Transmission/transsensor.jpg[/IMG] After I had the trans rebuilt I used a port in the drivers side of the case. The sender is the same size as the plug so that was easy. I don't have a pic, I think it was by the governor. |

Below is a pic of the drivers side of the trans. The bolt referenced is directly above (and slightly to the left) of the shifter shaft. [IMG]http://i161.photobucket.com/albums/t221/vrodpete/personalphotos159.jpg[/IMG] |

Awesome that makes sense. Thanks to you and Pete for the info on the sensor mounting. |

Welcome! If the hard lines are still there using those into the top of the cooler is fine. I ran all new line to keep it away from the headers. My stock lines were getting pretty rusty and I didn't like the routing to well. |
