I was trying to save some time and aggravation by buying a set of transmission cooling lines. Called Classic Tube and I$- L*&% tube. Both only referred to the 65 automatic trans as a power glide and said if I think it is a Jetway (T300) I would have to send in my lines to duplicate.
Who is crazy and do either of these companies current lines fit?
( Please refrain from answering the first question if it would hurt my ego)

I bought my automatic transmission lines for my jetaway transmission from in-line tube and they seem to fit fine. I still have not installed my radiator but it looks like the lines are going to line up with no problem.

( Please refrain from answering the first question if it would hurt my ego) A Powerglide and a Jetaway are the same basic trans. While there may be some slight internal differences, the case, line location and size are the same. Chevy called their 2-speed auto a Powerglide and Olds called it a Jetaway. |

Super Turbine 300, ST300, Jet-A-Way, Powerglide, POS, etc. All names people call the Olds 2 speed, which has a switch pitch converter. The Chevy powerglide does not.

That would be the "slight internal differences" I was speaking about. We all know that the switch pitch is a far superior trans  However, for the purposes of trans lines they are the same. |

Anyone found a supplier for pre-bent lines for a car with a TH400 installed?
Alternatively, I'd love to see pix of those of you who have a BBO (with headers) and TH400 installed to see how you routed the lines.

I never did get a response to my post above, so I thought I'd give it another try and queue this back up.  |

Not sure if there's a lot of difference in the set up of a TH400 versus a TH350 but I bent my own. Didn't know how they were routed so I bent them to go around the outside of the headers versus under the motor. Now that I know where they go, am planning to do it again. A good machine shop will have the tubing and a loaner bender. Just a thought if you can't find anything. |

If I remember correctly when I switched out my Jetaway for a TH350 (in Bud442's car), I used the original Jetaway trans lines without any mods. Bud might be able to back this up by looking under his car.

To get around the oil filter and housing, and between the headers and block/oil pan, do the lines dip down below the oil filter and housing, or somehow snake around it?

They go between the passenger side motor mount and over the cross member. There should be a bracket. See below:    The lines go through that silver bracket then to the radiator. Sorry but don't have a picture of how it looks from the side. |

Thanks! Very helpful.
It appears from the pic from above the transmission (you standing on the transmission mount) that the lines route to the outside of the oil filter and housing. Then I assume they must bend down and in so that they can pass through below the motor mount between the oil pan and frame.
Looks like that's going to run the lines very close to the headers (not much room between the oil filter and housing, and the headers), but looks like there's no way around it.

Found a better picture and your right. The lines go between the Oil Filter and Header and there isn't hardly any room. Since these lines are for cooling that could eventually be a problem as the headers throw off alot of heat. Don't know what I'll do yet but will probably try to route them a different way or insulate that area.  |

When i was running a TH400 I ran SS flex lines and plumb'd in a trans cooler. This gives you much more flexability. Not to mention you don't have to worry about kinks, vibrations, or rubbing on the frame anywhere.

Did you route them following approximately the same path as we're looking at here with the hard lines, or did you swing the braided lines out toward the fender well? When I originally swapped out the 330/Jetaway combo for a 455/TH-400 in 1986, I trashed the cooler lines... maybe I didn't think they'd work out. The thought of trying to route new hard lines in a completely assembled car seemed impossible to me, so I ended up using rubber power steering hose (I had no idea what kind of pressures the cooler lines carried) and routed them up over the upper control arm, attaching them to the inner fender well, and back down to the radiator cooler fittings. I never did like the way that looked, and thought one day I might put in new lines and carry them all the way behind the inner fender well, so they would be less noticeable, but I never did. Now the car is getting a complete home make-over.  The motor and tranny are sitting back in the car, but the entire front-end is off the car, so now I have the opportunity to install new cooler lines the "best" way. Of course there's still the issues of header clearance, etc...  BTW... if I decided to run braided line, would a #6 be the appropriate size? |
