High milage tranny maintenance

When I had some work done to my car my mechanic advised my not to even touch my tranny with 110,000 since it runs fine now. I wanted to update the accumulators and switch it over to mercon v and add a 24k b&m tranny cooler.


What would you do?

Quote from Silver95Bird:
A lot of people take a tranny that was 95% worn out, and change the fluid in a last ditch effort to save it. Then the tranny wears out, and they blame it on the fluid change. It's not the fluid change, its the high mileage with poor maintenance that failed the tranny. I'm not flaming you in any way, this is just a common thing we see around here. Some people dont think these things through.

The question is how well has the tranny been maintained up til now? If it's been changed every 30,000 like it should, I wouldn't hesitate to change the fluid. If it's got 110,000 miles and has never been changed... you might as well start saving for a new one. Nobody would ever run an engine for 110,000 miles without a oil/filter change, but people forget the trannies.

What would you do?
I added a B&M 24000 cooler 14 months ago, at about 200,000 miles. I did the J-mod, and went to synthetic fluid last August, at about 227,000 miles. Like Silver95Bird asked, how's the maintenance been on the transmission on your car? I've not had any problems, but I did do a few routine transmission fluid/filter changes before the upgrades...

see thats the thing I don't know. The car was a repo and there isn't even a owners manual in the glove box so who knows. I think one thing worth mentioning is the brake pedal is hardly worn actually it almost looks new.

Hmm, my car's got 67k on it. I doubt the fluid's ever been changed, though I hope to rectify that soon. Any point in bothering or just start saving?

67k is a lot different than 110k. I'd get Mercon V /cooler on there soon. THe 11/94+ cars have a better TC, which also helps tranny life.

I have no idea when my car was actually built. I'm assuming it's probably on a sticker somewhere?

1/94. Figures. Though if I'd thought about it, there's no way it could have been a '94 and still had a 11/94+ manuf date.

My T-Bird had two tranny fluid changes during it's first 110,000 miles. I switched over to MerconV and did the J-Mod at 140,000 miles. Just turned 200,700 miles, and has never been rebuilt. It is my daily interstate driver, averaging 23,000 miles per year.

NO auxiliary cooler, either.

Well I talked to the tranny shop I was going to have change my fluid and they are wanting 120 to do it with the merc v and he said 100 just for the install on the cooler. haha. Now I think I might just wait until I can find a warm place to do it and do it myself. I was doing some searching and it looks like I can change it myself for like 50 with merc v and a new filter right?

It seems the smartest to bypass the radiator tranny cooler. With my B&M 24k cooler what exactly do I need to purchase to bypass the radiator. This spring I might get the cobra radiator.

Living where you do I wouldn't bypass the radiator as it also serves to bring the fluid up to temp in winter

There is no limit to what you can acheive if you don't care who gets the credit.

Ok....I am starting to round up the parts that I need to do this. I have been searching and can't come up with a good way to do this install.....First priority is saftey...after reading some posts it made me visualize spining out in front of a semi or something crazy.


So right now I'm assuming that I need to splice into the top line.

I have an assortment of fittings/clamps that came with the b&m 24k cooler can I use these?

thanks

Yes there should be a brass fitting that screws right into the radiator, by the battery, it's included in the kit.

And if you're just doing the less than 300hp J-Mod there's no problem with it. I don't think you will spin out in front of anything with the medium or high settings either, but it's kind of overkill for your application.

Ok...So I unsrew the top line second fitting and insert the brass fitting that came with the kit and run the rubber line to the cooler. Then take the other peice that I buy from autozone from the cooler to the line? Should I just slide it over the line and put a few hose clamps on it?

BlackCat....no I'm not even doing the j-mod yet....What I meant was I don't want tranny fluid squirting/seeping from the connections. Fluid and rubber=spinout

thanks for the reply though

You'll likely want to get a new fitting to replace the one on the line itself - unless you find a fitting with Loooooong threads. the Ford design is the weirdest thing ive ever seen for a fitting like that. when you unscrew it from the radiator youll see what I mean. I got a normal 5/16" fitting and replaced the one on the line, then the B&M stuff bolted up easy.

So I need to unscrew the second fitting and cut the end off with a small pipe cutter.....I forget what the tool is called to taper the end of the line....and put a 5/16" fitting on it?

how many quarts will I need of Merc V?

13?

Reuse the stock gasket on the tranny pan....

When I had my 94 z I changed the filter and a little plastic piece stayed in the top of it.....are these filters a biatch to change?


I just don't want any surprises when I do this being a daily driver......can't have any more down time ie that stupid oil sending unit problem I had....

It's a flaring tool, it's for flare fittings. I think the problem w/ power flushing ancient fluid out of trannies is your pushing all the crud into places it can't be. Alot of shops are tossing their power flushers for that reason. Remember, ATF is super detergent based. It used to be common practice to dump it down carb throats to clean rings/valves. It was fun to fill towns w/ white smoke. I remember guys using a little to cut the grease on their hands. We're lucky enough to have drain plugs on our TC's, just use them and maybe blow out your cooler w/ light air pressure. You could just drop the pan-drain-button up anf re-fill but leave the TC full and repeat 3 or four times over a month or so w/ Merc III, then do the filter and Merc V. Then you will slowly be getting rid of the crud little by little.

Yes, youll need a flaring tool. Just drop the pan and remove the TC plug. When you remove the filter the seal (little orange o-ring) may stay in its bore, pull it out with a small screwdriver. Torque the Plug to 22 FT-lbs and the pan bolts to 120 IN-lbs. Refill with 13qts mercon V. Might not hurt to have a spare qt just in case with an extra cooler.

Do flaring tools cost much? When I did the 4-wheel disk conversion on my old stang my buddy had one. Or should I just rent one from autozone?


Thanks for the replys

I'm sure autozone sells them, I dont remember them being expensive either.

Cool....Should I assume I can get mercon V from there as well?

Man I can't decide if I should just drop the pan and change the filter and add 6 quarts of mercon III or just do the big daddy since I was getting a little bit of shudder but it has stopped for the most part or just put the cooler on and add a quart.

I might end up moving out to California here in a week or two. So reliabilty has to be a key right now.....If something happens after I get there then so be it. I just don't want to be crusing and something snaps before I get there.

Well no matter what use mercon V. its about the same cost as 3, so theres really no advantage to it. If you're dropping the pan to do the j-mod I'd just drain the TC and do a full swap. If you're just doing the cooler for now and the j-mod/filter change later then thats cool too.

I think I might tackle this tommorrow....

Parts:

1. 14 qts. Mercon V
2. Filter
3. Flaring Tool
4. 5/16" fitting
5. 5' of extra hose
6. ??????

Reuse pan gasket correct? Should I buy some type of spray type adhessive or something?

One last question I had was....when I put the car in drive after it has warmed up/sometimes cold it has a little bit of a delay before the tranny catches. please tell me this isn't major.

Besides that the car feels great....hopefully this fluid and cooler will help the tranny last me at least another year.

Silver95Bird - you've been very helpful.....thanks

The trans. pan gasket is reusable yes. It's made to last the life of the trans.

How long of a delay are you talking about before it goes into gear?
