Hi guys, i'm wonrdering if anyone here has tried using the tranny seafoam, and whether it yields any positive results ? abcI30 is going to help me seafoam my engine this weekend, so i'm wondering about the tranny treatment as well. My AUTO tranny has an occasional "shudder" when switching from 3rd to 4th @ about 1700rpm when rolling downhill or on a level road when i ease on the throttle (it shifts seamlessly @ 2,000-2200rpm, but then i'd be doing 50mi/h in a 25mi/h zone while it's raining ) I actually had the ATF drained (not flushed) about a thousand miles ago (unfortunately i didn't know about seafoam @ that time)

 

buh-ump

 

Id pass on it, order a bottle of Auto-Rx (google that) add half the bottle, drive for 1000 miles, go get her flushed, it should shift much much better, Im just finishing this up on my 98 I30, and am truely shocked at how well its worked, i knew it would help, but not this much...

 

not trying to go off topic or anything... but...

could that harm the trans by loosing up crap and stuff? i didn't know... and its prob a dumb question... just my .000002 cents.

 

kcryan, thanks for your reply! I'm glad to hear that Auto-RX actually works. I actually just bought the transtune. I figured that if the engine seafoam works as well as people say, the trannny one shouldn't dissappoint either.

to twoconfusedants: Supposedly that's what seafoam is supposed to do: "Loosen gunk" i guess that's why they reccomend a flush.

 

Auto-rx works slowly so the filter has a chance to grab it, and it doesnt knock it off in globs, so it wont clog anything, others work quicker.


Transtune will prob be fine, if it were me id return it for the ARX, but i will admit i love that stuff.

Good luck

 

thanks, dude

So there are no people that have used this stuf?

 

I like the sound of this. . . my beater might get this treatment. You can find it in local auto stores?

 

If you're talking about Auto-RX, you neeed to order it onilne.

 

Worth the wait fellas, well well worth the wait

 

kcryan, how many miles are on your sophisticated maxima ?

 

bump.......

 

I've used Seafoam in the tranny ('96) with 190K km on it. Used it due to my CEL came on indicating tranny valve body issues. Put in half a pint of Seafoam and within 2 days the CEL light went out. Ran it for another two days and drained the ATF and of course refilled it. The CEL light didn't come on again, (over a month now) and the tranny shifts fine. Before Seafoam I did notice odd shifting into overdrive, where I don't notice anything unusual anymore. So far so good. I've also used Seafoam in the gas tank and crankcase without issues.

 

thanks ChrisZ, i really appreciate your input!!! abcI30, just helped me do a litlle tune-up yesterday. We seafoamed the engine thru the BB line and put some in the gas tank. (i'll put some in the crankcase when i'm about to change the oil) I'm glad to hear you seeing good results. I guess i'll see if i can ask acI30 to do a drain/re-fill after i treat mine. I'm also considering switching to Mobil 1 synthetic ATF, i can switch with just a drain/refill right?

 

bummppppp..............

 

Just a drain/refil is what I did. I'm sure there is a little Seafoam still left over, but I'm not worried.

 

I have used the Seafoam Trans tune in my Grand Cherokee 5.9's automatic many times and seems to help it shift better each time. It is supposed to help dry the clutches in the tranny or something.

 

koooool Thanks, so i can switch to Mobil 1 synthetic ATF after running transtune and doing a drain/refill?

 

I did once use the Mobil synthetic ATF, (drain/fill). Didn't notice any performance improvements over regular ATF, but did notice a hit in the pocketbook! Went back to regular ATF after Seafoaming.

 

lol, gotcha, thanks again ChrisZ

 

Sorry to resurrect this thread, but i just HAD to share my recent experience! A fellow .orger help me change my engine oil as well as the ATF. I put in a little over 1/2 a pint of seafoam transtune in the tranny and drove around for 7 miles. When we drained the ATF, we put in Mobil 1 Synthetic ATF. WOW! What a difference! The rough cold 1-2 shift is history, the tranny shifts better across the board! It also smoothed out my dreaded 3-4th shift. (though i still drive with O/D off when goin' below 40mi/h in city traffic)

 

bumpski for anyone who's interested.

 

I guess it started just now Or when i seafoamed the engine

 

This is generally a bad idea. Manufacturer recommended Nissan Matic D or Dextron 3 is what we should be running in our auto trans. I'm not saying that if you fill with up w/ Mobil 1 your transmission is going to explode, but auto trans runs a lot hotter than manual, so you do run the risk of blowing out a few seals, not to mention the price difference. You want to upgrade your trans, flush it out, clean the filter, and upgrade your VB. Done.

 

why is this a bad idea? arent synthetics known for their higher resistance to thermal breakdown? have you actually tried it or know anyone who has had problems as a result or are you guessing?

 

Mobil 1 Synth ATF is dextron V (which is backwards compatible with III, as far as i know)

Not to mention the fact that i have 128K miles on my tranny and therefore can't do a flush or drop the pan. I figured that what i ended up doing was the best option.

 

to update the thread

Since i've used transtine, and switched to Mobil 1 Synthetic ATF; I've had an improvement in the notorious rough cold 1-2 shift (mostly due to the ATF). Overall, as soon as it reaches operating temp, the shifts are seamless!! (except for the 3rd-4th shift, wihch might be due to loose tranny mounts)

If you like peace of mind, then do it!

 

dont know about for the tranny but it fixed my power steering problem. I am truly amazed.

 

what was your problem, man?

 

I actually drained my old PSF by disconnecting the hoses to the reservour, and put in Mobil 1 Synthetic ATF) Maybe next year, i'll do the same procedure, but put in a little transtune before draining.

 

Steeringwas pretty much rock solid unless the car was in motion. Did a real flush (not that motorvate crap) and it didnt help at all. tried auto-rx and nada. i was told i would prob have to replace teh rack. figured what the hell and tried the transtune. 3 days later it was free (except for right at startup). I personally would never use it in my tranny though .

 

glad to hear that you got it worked-out
