AMC TH400 or GM TH350

Why not a tf727 with a d300 bolted to it?

Why not a tf727 with a d300 bolted to it?

Im not a big fan of the T350 the T400 is a good tranny but the 727 IF done correctly is a damn good piece of aluminium for a slush box and you can put the D300 right up behind it. the 700 R4 requires a healthy build blue clutch packs and such.

A buddy of mine is in the process of putting a built 700R4 behind his mildly built 401 in a 77 cherokee tow rig with 35's, D44/D60 and 4.88 gears. the T400 works fine but the Q trac keep shelling out seals. and he figures if he is going to spend the cash on changing to a different tcase adding an OD at the same time sure would be handy

A 700r4 would be nice and I'll start looking around for one. The reason i was interested in the 400 or 350 was for saving some $$$. The 727 would also be nice, but expensive to find one not already toast and to have it built 'right'. I have a q-track th400 in another donor vehicle and gm th350's are cheap as dirt. Also I have a np205 for a 350 already. and a few th400 jeep d20's.
Right now I am leaning towards the 400. I think it will be cheapest to do and most reliable. Really I'm not sure if I am even going to switch yet because I love my manual tranny, but this jeep is my sand, mud, street jeep and an auto would be faster

727's were pretty easy to come by in 80's waggoneers, most i have nabbed werent toast and worked pretty well

where in Nor Cal are you?

[HotJimmy]

I'm in the foothills, but work in the SF Bay area. I talked to a few friends who have a 727in their CJ5's and they love them, but said if it does go out the case is usually wasted. Said it happened once to him with his 401.
As for finding one, I don't think it will be too hard. Wagoneers are pretty common in the wrecking yards out here

Jimmy how's your project?

I picked up my 360 on Fri and started cleaning the shop for the R&R with the I-6. I'm still looking for a reliable tranny (don't think the 5-spd Tremec will hold up.



So when I was at the shop today I asked Raleigh about the TH400 he has on the floor (and has been there - at least 6-7 months) It's on consignment said he'll give the guy a call on his lowest price. There are a couple things I'm not sure of ...
1) It's got an 8,000 stall converter - is that a bad thing
2) It's only a 3spd
3) Installed in a restoration for about 3 months, and ran fine when pulled.
The owner replaced it with the OEM tranny when he sold the car on E-bay (it was a full frame off resto that Raleighs company did and the OEM tranny was part matched to the car - owner got close to $100K for the car) so I'm looking at the 'left over' tranny
4) Oh yea ... It was built by TCI

So, I need what to make this work?
$700
The tranny/t-case adaptor (Novak P/N 134)
block::belhousing ?
An extra 12-14" in frame length

Is it even worth considering?

[jeepsr4ever]

You will need the chevy to AMC bellhousing adaptor plate and the tranny to T-case adaptor

I say just go ahead and get what you want - a 700R4 from TCI. Trust me, not having the overdrive blows. I had a TH400 in my last Jeep, and while it was almost bombproof in such a small vehicle, I always wanted a overdrive. If you are gonna go 3 speed auto, then just grab a 727 from a waggy - no adapters needed for your 360//dana 300 setup - that's what I am running and you have enough lift that clearance won't be a problem.
Just my .02

Oh yeah, and that motor sure is purty!!

[Mudrat]

Oh yeah, and that motor sure is purty!!

PURTY? PURTY!! It's freaking GEORGIOUS (and paid for) - I'm not gunna run it I'm gunna FRAME it
Yeah, I know about the overdrive thing. I'm hoping the 5-spd holds up long enough to get the $$$ to get a stout tranny with over drive ... NV3550?? I like jamming gears, but I like to drink coffee while I do, so maybe a slush box ultimately???
