Did the post search to find any info i could get but nothing concrete.

Is it overkill to add an external tranny filter to an automatic VG tranny?

I want to get the most out of my tranny as i can since i had to replace it because i blew a line on it last year and trashed to old one. the radiator is new as are all the lines and i have been keeping up on the fluid changes.

Hear is what i am considering.

External filter along with the 2nd flush since installed.
External cooler

Also what is your opinion on fluid additives. any good ones or all they a bad ideas?

Opinions and thoughts welcome

Thank you

 

don't bother with additives but do run the filter, cooler, and use synthetic fluid.

 

the idea is sound in theory. I do not think it would hurt. my only concern would be bleeding it after initial install, but it shouldn't be much more difficult than when the transmission was replaced, and you re-hooked it to the cooler lines.
That, backed by the extra cooler should help a little.

as for additives, I do not know. I know Lucas makes some good additives, in general, but I don't know how well they work with VG autos.

 

the trans has a breather hose to bleed itself.

 

Where would the optimal location be for the cooler? In front of or behind the radiator.
I'm nervous about running the tranny to cold in winter and would think bottom rear of the radiator may be best.

 

Good thread to read---> http://forums.maxima.org/3rd-generat...ler-today.html

 

Forget about putting external filter for the tranny but external coolar will help if u r driving u car alot and putting so much load on it most of the time but doesnt hurt either jus for extra cooling. And plz don put any extra filter on ur tranny as auto trannies r already very sensitive to the volume and the pressure of the fluid by putting extra filter u r jus disturbing all dat

 

I would put it behind if it were possible
I know around here the trans fluid gets WAY to cold so shifting is seriously delayed until it warms up. behind the radiator (not really possible because of the rad fan assembly) would be best as it would pick up heat coming off the radiator and bring it up to temp faster.

in the thread wayne mentioned we discussed the idea of a thermostat system but never found one IIRC. Shame...

 

I just use a cardboard cover on the cooler in winter, but yeah i really couldn't find anything thermostat wise that was worth the $$, time, and trouble to install.

And yes, it definitely needs a cover on it in the winter!! the trans fluid will not warm up enough for the trans to shift correctly, also it will not go into OD(final torque converter lock-up) with a uncovered cooler in cold weather.

 

you found a tstat?

 

I found "something" that might/could have worked for one, but iirc, it was much $$. I don't even recall where i found it.

as far as a t-stat this is what i found. a bit pricy but i guess in the long run it will do the job.

 

i'll take pics of my set up when i get home tonight.

here's the basic set up...
this is hooked up from the tranny cooler lines.


it's a oil filter adapter with t-stat. when the atf is cold it will just filter and not flow any fluid to the cooler. once the oil (ATF in this case) warms up the fluid will start taking a run to the cooler after the filter and then goes back into the tranny. the cooler is a B&M stack plate cooler. the stack plate will allow fluid to go into part of the cooler when it's cold and when the fluid warms up it will then flow into the rest of the cooler. i used a pretty big cooler since i have the t-stat so no more over cooling. all of the plumbing are running AN lines and some hard alum lines.

i'm using Fram racing or the K&N filter on it. it's a 1qt filter to help with cooling and filtering.

the first time the filter goes on you'll need to change the filter within 1000 miles and the filter is going to be real heavy. after a few filter changes you can swap filters every 5000 to 6000 depends on how rough are you on the tranny.

when my tranny finally worn out the rebuilder noted that the fluid was perfectly clean but the age of the tranny it was just worn out...but he did say the fluid was really good....so good that he never seen it so clean.

 

what the heck is that?

 

Do you have a part number or where you got this set up from sounds like exactly what i am looking for!

it's about 90 bucks for the adapter. you pick what filter you want to run (ferd or chebby).

i used a chevy one since they have nice big filter available for them.

the cooler you can pick up from pep gurls or local parts store (summit, jegs). then just get your lines and fittings.

 

great. thank you for your help.

 

wow 85 bucks this seems pretty cheap if it allows you to run a proper tranny cooler without overcooling i might consider this as well
how cheap is the hardware and where do you mount this thing? and how many miles did you have this on before the tranny you talked about broke down?

 

filter was installed around 100K...it started to slip at like 139K

 

Doesn't matter, it was doomed from the beginning..

 

pretty much...but it was running redline atf at like 80K.

i was the king of street light drag racing. it's all about 0-35 and then 35-0 at the red light..LOL

 

That sandwich adapter is for a engine oil filter base not a transmission, it actually fits between the oil filter and the engine block (that's why it's call a sandwich adapter). This is what you need either the Standard kit (10678) or the deluxe kit (10677) from Perma -Cool (www.perma-cool.com)

 

crap you're right...i linked the wrong part..let me get the right part on that.

 

ok i looked at my set up again...you're right...

you need to set up a remote filter head...then sandwich the mocal oil adapter on it. once that's done you spin your oil filter on the sandwich adapter and you should be good.

 

hang on let me see if i understand this. i threw this together in CAD really fast.

 

so you use an engine oil filter and transmission fluid remote filter head with a "mocal" oil adapter?

 

Take this...(two ports comes from/to your tranny)


throw this under it....(two ports comes from/to your tranny cooler)
cooler ---->

then spin the filter on it....


add hoses and line fittings.

if you still don't understand i'll come over and hit you over the head w/ a tack hammer.

 

In for more pics of dan's car..

Ok i get it. i was having trouble seeing how it would bypass in the sandwich. well all together im looking at $200 for the whole job.

im looking at the layout perma-cool has on this page and i will most likely use that with the thermostat to have a quick warm up on cold days.

great. thank you!

 

Why all that? There are thermostatically controlled remote filter mounts, no need for all that sandwich adapter stuff......go visit the Perma-cool they're the real deal.
