Default 4T60-E Trans cooling question

I know right now that the transmission exchanges heat through the radiator, but, can I completely eliminate that and just go with a trans cooler out front, keeping it on the drivers side?

That'* what I have...I figured the line runs would then be much shorter and put less stress on the pump.

I just put that one on last week, along with a new radiator and two tranny lines.

Bought a 'u-turn' fitting (looked for the link and can't find it now) and screwed it on at the top (tranny line intake) of the radiator. Mounted the oil cooler at the base of the crossmember in front of the condensor cooler to secure it, and used a bracket to reach from the top of the cooler to another metal piece under the radiator cover. Then simply popped a fitting on to the top tranny line, running rubber to the far 'intake' of the cooler, then back to the 'u-turn' fitting.

While I elected to use both cooling systems since the radiator was new, you can also bypass the radiator cooler, about which you asked. The tranny oil definately runs cooler, around 165 degrees on a 90+ degree day with tons of idling in traffic. It ran over 185 and higher before in similar conditions.

(Everything I needed came in the cooler box; brackets, fittings, and line.)

Yeah saw the massive amount of install parts which is great and why I bought this unit...I don't know what'* going on...when it'* 80+ out the car can lose overdrive especially it seems with the a/c on so maybe it'* not flowing correctly or just getting too hot (which the fluid indicates, it'* not brown but it'* not happy pink either). I don't want to put a strain on ye old transmission pump so I figured the best way to do this was a short line right keeping it on the left straight to the new cooler and back to the trans. It'* Long Island so it doesn't ever get really TOO cold here, and if I see a problem in winter I'll just cover it a bit. I figure on mounting it towards the bottom with brackets?

Any cooling is better than nothing. Especially with a lot of city driving. If you can, locate the cooler in front of a/c radiator so it gets first dibs on the cool air.

Mine went on a '94 Delta, but I can't say your core support is similar. That being said, I had the car on a lift and just in front of the condenser at the passenger side of the radiator was a a strip of support with a rubber edge. I lift the rubber and there were already several factory holes. I used one of them for one side of the bottom of the cooler and drilled a quick hole for the other side. Using one of the supplied flat brackets, I bent the top 1" at a 90 degree angle and stretched it from the top of the cooler forward, so it bolted right to yet another strip of core support.

I wonder if your in-line radiator cooler is clogged, it happens.

I was thinking the in-line cooler may be clogged...that'* why I'm eliminating it...straight to the new trans cooler and back. Hopefully do this Sunday weather permitting.

Another question here, I want to use part of the existing line to hook the new rubber hose going to the aux cooler into. If you take a look at the image below:



See where the rubber is? I want to remove that from the metal and put the new rubber hose in there. Those are the stock lines, it comes metal up to infront of the sidepan of the trans (I can easily get to it), the rubber makes the turn, then it continues as metal to the radiator. I basically want to put the rubber hose I have in place and route it driver'* side to infront of the condenser (which I have found room) to the aux cooler. How can removing the rubber and replacing with my rubber hose be achieved? Anyone do this? Other ideas?

From the picture, it looks like you can cut the steel line just ahead of the rubber line, and place a tight fitting piece of rubber hose on the cut end with a clamp or two. Make sure to cut it where you have 1" to 2" of straight section, not on a bend.
