Is this VB gasket, or clutch material?

What are we looking at? It doesn't look like clutch material to me.
-
Valve body off a 700r4

looks like the valve body gasket to me.

gasket..

Gasket

Yeah that's what it ended up being.
Still not 100% happy with the shifts.
Gonna put an nv3500 5 speed in it when I get one.
6.2 diesel plus 5 speed manual could equal 30 mpg highway

Maybe in a Corvette....
NV3500 is kinda weak for a 6.2, but I guess you can probably get 10 of them for the price of a 4500.
Do you have a diesel governor in it?
What's wrong with the shift feel?

It's the original 700r4, so it has the diesel governor. It started having real high line pressure and delaying the 1-2, and when it finally shifted it banged. So I pulled the valve body and checked for a stickin tv valve.. Valve wasn't stickin, but the photo from the original post is what I found just above the tv. So I thought that was it. Put it all back together and now when cold, it shifts just right; second by about 5 mph and third around 20. Soon as the cold start drops off it holds first till 15-20 no matter what. Doesn't bang as bad (put a spring under the second accumulator) but still shifts real late. How long till a 230k mile 1989 700r4 craps out you know? So I'm hoping to stick a five speed in it, but getting the nv3500 is not easy in VA evidently
-
That is a lot of miles.
Tried slacking the TV cable adjuster a tooth or two?
Also sometimes the gov gear apple cores on those, probably worth a peek in there first.
PS. I'm starting to want a 700 instead of the 400 behind my 6.2.
-
unhooking the tv cable does nothing. I'll try the governor this weekend

i WOULD NOT use a NV3550 behind a 6.2d
and theres no way you will ever see 30mpg from a 6.2 in any truck..

I don't know if I would either.. But the nv3500 is the one I was speaking of. The truck got 24.3 going back forth on a 7 mile journey for 31 gallons, with the original, 230k 700r4 behind that 6.2.
Also, the nv3500 came behind the 4.3l v6 which made similar hp/trq and the behind the 5.0 v8 which beat out the 6.2 on both.
Wasn't until the 6.5 turbo that that they went to the nv4500

they die behind stock 4.3L V6 engines tho..
they ALL DIE..
they had horribly weak syncros...
-
I never have seen a nv3500 have a failure death. I have seen several of them and even several 4500 with syncros that were out between 2nd and 3rd. If you slowed your shift it would be fine, but never have I seen on leave someone stranded. I am not saying it would be a good or bad choice for the 6.2 but I think it is a better unit than you give it credit for.

MOST have bad syncros..
my cousins doesnt even have a syncro left in it.. you gotta shift REALLY SLOW..
if you bolt a 3550 up to your 6.2, i wish you luck..
-
Another thing to take into consideration is the weight, the nv3500 only came in light vehicles that weren't geared towards towing duties... I don't know exactly how you drive or use your truck.
-
a buddy of mine has a nv4500 behind a 350 chevy, with practically no syncros...lots of fun riding with him, revving the engine all over the place grinding the gears like mad trying to get into the next gear, he doesn't seem to understand the concept of shifting a non-syncro transmission. ;D
-
Just to be clear again, I have the 3 5 5 0 Not a 3 5 0 0. I have an NV4500 in my 2500HD chevy. The PO put 90wt in it and 2nd always grinds now, other than that I have towed and worked it a lot and it takes a beating *step 1 putting syncromesh into it*.
In all the jeep forums I have read they say that the ax15 is maybe good for 10hp more than the NV3550. They have stated that both are good trans for a 4.0L jeep or a mildly built small block. I couldn't find an ax15 and I found the NV for about as much as a rebuild kit and it came out of a 39,000 mile jeep. So that is why I am doing it this way. I personally think the NV 4500 is quite a trans and hopefully the 3550 will be similar for this wrangler that is 1/3 the weight of my truck and less power too.
