Agreed.

speedy13 · 10-10-2005, 01:12 AM

no,but on a brighter note,I feel the chrysler tranny is better built then the mitsu.

XMasta19 · 10-10-2005, 09:10 AM

Chrysler builds the worst transmissions of the Big 3 American Manufactures. Its a well documented fact, after the Torque Glide 400 went away in the 70's they started building crap. But to answer your question no it would not work, diffrent bolt pattern, diffrent starter placement, diffrent just about everything else.

speedy13 · 10-23-2005, 03:57 AM

while this may be true,mitsu isn't one of the big 3.have you ever shifted a 2Gnt?I have,i had one,and a person with a stub could shift gears in it.It feels great,can't say the same for my tsi awd,or other 1gs and 2gs iv'e driven or been in.My old roomate rebuilds tranys for a living and he sees alot more mitsu eclipse tranies then the Chrysler manual version.While the turbo tranies are taking more abuse,they still don't seem as smooth and well behaved as the NVT-350 from Chrysler.I can't say the same for the auto tranies built by Chrysler,they feel like crap,but so do the mitsu ones,but the turbo makes up for it i guess

i must conquer with the man above this post.....it just glliidddeeessss into gear and man is it smooth unless you suck at shifting.I love em. I rather have a american made tranny or engine rather then foreign b/c they have better metal. Although sometime the mits and other trannys last long its more of the gears not the casings.

Chrysler does not manufacture the manual transmissions in the 2GNT. They use transmissions made by the New Venture Gear corporation. You can find a NV-T### tranny in most DCX vehicles with a MTX. I saw an article somewhere about a football player who had a Viper V10 installed in his Jeep Wrangler with a special NV-T750 or something.

Just thought I would clear that up.

Kthx.

BigRand · 10-23-2005, 03:01 PM

agreed, now do u think these guys at NVT could make me a Throw out bearing that isnt' part plastic. I've had two go out on me, and I know a lot of other people who've had TOB problems too.

speedy13 · 10-23-2005, 11:30 PM

sach's TOB isn't plastic.BTW nice info on the chrystler tranies,didn't know that one.would make sense huh,NVT=new venture trans...

BigRand · 10-24-2005, 12:16 AM

Well the ones that keep coming with my clutches for my 420a tranny are part plastic. They aren't full metal like most normal cars.

I've had a couple of them heat up on me, melt themselves onto the input shaft outter ring, and then stick on to it, then eventually yank it right off. It caused me to replace 2 trannies already, but I'm looking forward to building a strong tranny with neon parts and LSD.

Rats, I knew that. Doug pointed that out some time ago. My mistake.

napkinthief · 10-25-2005, 08:37 AM

would an srt4 tranny bolt onto a 420a, since the engine from the neon is the same as the one off my nt

BigRand · 10-25-2005, 10:30 AM

Doubt it, as the bell housing between the eclipse and neon are slightly different, but I'm sure you could use the parts and just wrap it in the eclipse 420a bell housing.

You can't use the SRT4 tranny. Period.

It does not use a regular Neon transmission. The gearing is different, axles are different, the bellshousing is different, the block it mates to is different. It's all different. You can't even use the 2.4L block out of the SRT4 for your 2.4L conversion. Just erase any thoughts relating to anything SRT4-related being of use to you right out of your mind. They are pointless.

If you drive a 2GNT, you are limited to ONLY the stock NV-T350 transmission or whatever 2.0L Neon transmission has the 3.55 gears in it. In THAT case, you would need to reuse your own bellhousing and do more of your own research as to how to do it. (Assuming manual trans, as ATX is not performance oriented imo.)

Thank you. Have a nice day.

TotalEclipse112 · 10-25-2005, 12:48 PM

SRT4=2.4l motor 420A=2.0l motor Once again they are completly diffrent. The 2gnt has nothing in common with the SRT4 motor wise other than they are built by Chrysler. If you want to use Neon parts find one from 95-99 those parts should match right up.

Sorry for bringing up an old thread, but well I figured I do something crazy, and search first haha!

Well I know the SRT4 trans wont bolt-up (my original question), but I wonder if the gears would work in the 420A trans? I like my 99 RS as a DD, but I hate the gearing of it cause going 75mph on the highway Im at 3500rpm, and I'd like to have that under 3k to save gas due to driving around 50-100 miles a day.

Thanks for any help guys.

Use the neon 3.55. I'm running it right now and I'm 2350 @ 70. But I'm not so sure that you will save gas (unless you drive like an old lady). I tend to find myself sitting in fourth too often. That is with 10.5 comp but stock TB and stock cams running on the stock ECU. My car is slow right now, lol.

The srt-4 gears will not work.
