Stand alone cooler for transmission

Post #1 by lahti35 » Thu Jul 27, 2017 11:20 am

As part of my "rugged as nails" '64 Falcon wagon build I'm divorcing the trans cooler from the radiator and installing purpose built items for each since we'll be towing a light camper.

Where is a good place to install an aftermarket trans cooler?

Most of the trans coolers I have installed are mounted in front or behind the radiator depending on the room available or if it also has Air Conditioning and is then hooked up in series with the radiators lower trans lines, this works very well. Often this is one the very first Mods that I will do to my personal cars and trucks to protect the transmission by installing a good aftermarket trans cooler and Trans Go shift kit. On my 1956 F350 transport truck (car hauler) the trans cooler was mounted behind and slightly below the bottom of the radiator (Horizontally) it was also not connected to the radiator it seemed to work quite well. Good luck :nod:

Thanks bubba!

I'll probably go low with it in front of the radiator with an 1" stand off and see how it does.... :D

I took the transmission apart last night and its got 3 friction discs in each drum so i'll be upgrading to V8 drums.

I am going to install the SK4L Transgo shift kit for 64-66 C4's. I was also considering changing the servo from a Z (about 2.5") to a H (about 3")... will that mess with the Transgo shift kit or are the two mods compatible?

The V8 drum upgrade is great idea for more durability! The Servo upgrade will be fine with the TransGo shift kit they are compatable, the H will give more holding power, the comman C servo would also work well. You should consider using a 1967 to 69 valve body though instead of the Duel Range 1964 to 66. The later Select Shift valve body will give much better (Quicker) shifting reducing slippage which creates heat, reduces wear, with maybe a slite bonus in fuel economy, and its a drop in bolt in mod. If you can find a 1967 to 69 V8 C4 core you would get the better most all your parts togeather. Ie the V8 Drums and Valve body. In that case you would use the SK4SL shift kit. The 1970 up 9 bolt valve body's can also be bolted into the early C4 cases by using a bolt and nut in the extra hole depending on the year though they would use a different part number shift kit. Good luck on the C4 build up. :thumbup: :nod:

You don't think the H or the C servo along with a shift kit would be too much for the stock bands and 24 spline input shaft? I have an A servo floating around and I was debating installing that since its bigger than the Z but I don't have the high power engine that folks put the H and especially the C servo in for.

On a happy note I discovered last night the tranny is a '68 instead of a 64-66 like I thought after finding the part numbers on the case and valve body... I found the V8 clutch drums for a very reasonable cost so I should be set with a rebuild kit and some new bushings.

:beer: Yes that is very good news that you have a 1968 trans! So if you have the 1968 Six Cylinder C4 you can use the SK4S Trans Go shift kit. Don't worry the stock Ford C4 bands are plenty strong they can handle around 400 HP. The A servo could work well too. The only ones I don't care to use is the B servo or others that were designed for use with a 6 cylinder and other low power engines. This is why I like to use the 1971 up C4's trans because of the bigger input shaft plus they have all the rest of the Ford Factory improvements also. Yes the 24 spline input is a weak point though not sure that it's all that bad in the case of using it with a six like a 200 or smaller. Of corse if you were able to pick up the 1971 up V8 drums for reasonable price then you could also use the bigger input shaft which would cure all the weak points of the early C4's. The thing to remember is that the shift kit is going to make the trans shift faster, it's not going to make it into a race trans with real hard shifts. One other thing you can do is pick up an adjustable vacuum modulator if your trans doesn't already have one that can help you dial in the shift firmness you like. Good luck :nod:

I didn't know you could use the later V8 drums... the ones I got are for the earlier C4. I'd probably have to change the pump too to fit the larger shaft... i'll be ok I think, its just a stock 200, I can't think of a time I ever head someone broke a 24 spline shaft behind a 6.

Good to know the shift kits just speed up the gear change, I didn't want things banging into gear anyway... just a nice shift in the wagon better than the 2 speed that was in there before.

Thanks for the advice bubba!

so would a person be able to build a 1967 F100 I6 C4 to V8 specs along with the Transgo shift kit? thanks

Yes there is great parts interchangeability with the C4's. Have you already made a positive ID that your 1967 F100 actually has a C4 trans? Many of those Ford trucks used the older cast iron case Cruse O Matic's / FMX, if you post some pictures we can help you I'd it or else check your trans tag numbers and door code. Good luck :nod:

Ok will do, if it's the Crus O Matic/FMX are they upgradable as well? As far as I'd numbers where would you look on the trans itself? I only ask because I'm gonna have to do some scraping as it's still attached to the truck. As far as toughness or desirability goes how does the fore mentioned trans rate?

They are very good transmissions tuff enough for truck use, they are upgradeable too the same as a C4. Most Ford auto transmissions have the ID tag mounted on the passenger side on the servo. Good luck :nod:

yes I have the C4 trans as I just did a trans service. The C4 has 11 screws in the pan and the FMX has 17 I believe. I ordered the C4 kit and it fit along with the gasket.

also at upshift from second to drive if I don't keep the gas steadily going faster I get a rev in the engine as if I shifted into neutral and then it will shift, is this a slip? or an adjustment issue? The truck has not been ran in almost 20 years but the transmission is getting better at kick down etc..
