Manual Trans Differents

GTMaracucho · Post by **GTMaracucho** » Wed Jul 29, 2009 12:31 am

Are There different between 1gn and 2gn manual trans?? Some friend of mine said me that the 1gn are different on synchro and for this use different oil fluid??

Sorry for my bad english.

well, the clutches are different. First gens used the cable clutch and second gens use a hydraulic setup. As far as the gearing, there are differences in the ACR/RT/SRT-4 and the base neons. The base 5-speeds have a final gear that is better for fuel economy on the highway, while the ACR/RT's have a different final gear that won't get the better fuel economy.

There was a change made to the later 2nd gen trans (all SRT-4s for that matter) starting in late 2002 production. Chrysler added friction material to the shift forks (and possibly the sycro rings themselves iirc) which made the use of ATF+4 necessary. If that is what you are referring to.

It is worth noting that the earlier year 2nd gen's actually utilized a cable clutch, too.

2000 only. Although there is a rumor of a couple 2001's that were made with the cable clutch, but this hasn't been proven as far as I know.

Thanks...but Can I use ATF+4 on 1gn trans??

You can. ATF+4 is backwards compatible. That and you really can't find ATF+3 any more.

The earlier 5sp trans had some special fluid that Dodge sold. Part #4874465...MSRP $19.70 per qt

Redline MTL is a good substitute.

Pennzoil synchromesh is listed to go in the t350 trans as well.

DO NOT PUT ATF+4 in your MTX. It was a change chrysler made to save money.

Listen to what Drakito says.

Listen to what Drakito says.

You beat me to it

Plus, there was no chance that the guy filling transmissions on the line could screw up and put the wrong stuff in the wrong trans.

From a reliable source, Mobil1 10W-40 High Mileage engine oil is the best thing you can run in your T350, T355, or T850. Just put 3 quarts in the '01 ACR the other day

ATF is a HYDRAULIC fluid, intended for being pressurized, as in a power steering pump, fork lift mast pumps, or an AUTOMATIC transmission. That's what ATF stands for, Automatic Transmission Fluid. A manual transmission is just a big gear box, and therefore needs something intended for metal on metal requirements. ATF does not have the lubricating properties required by the stresses that a gear box experiences.
In addition to that (re: common problem w/SRT4 T850), they added an organic compound friction modifier to the T850 to "help" the Quaife spin smoother. This friction modifier, which is intended for RWD differentials that run a GEAR LUBE (ever hear of someone w/RWD putting ATF in the differential?), reacts with the ATF to create acid, which in turn begins to destroy the fibroid synchros. If you add this friction modifier to a T350 that has ATF in it, the same thing will happen.

hmmmm, very interesting. And I was severely critizied on the big org for even suggesting that a manual trans could take oil, like the old FWD Dodge transmissions did.

I use Royal Purple Synchromesh. Works like a charm.

Just remember: the owner's manual and/or FSM is not always correct.

My thoughts exactly. 5w30 in all the old turbo Dodge transmissions. I'm sure you know by now that 1 in 1000 people on the other .org have any freaking clue as to what they're talking about. These are the same people that told me I couldn't use red Mopar sealant on a 2.4 bedplate. My transmission has about 78k miles on it, all of which are from me. It's probably time to put something better in there.

Well, enough about lubrication. Here's some info about gear changes and torque ratings: http://www.neons.org/forumdodge/trans.htm
