Looking good! Whatever else you do, run the correct oil in this trans! It calls for Castrol Syntorque, but IIRC, is not availiable outside a dealer. Check out Ford and Chrysler for pricing, as all of the big three used this gearbox.

If you use the wrong oil, the clutch facings on the synchros peels off, and will F up the bearings to the point of catastrophic failure very quickly.

Also, these were known for the 5th gear nut backing off.... mostly in Chrysler products, but it does happen. There is a clamp nut kit availiable to remedy this if it happens.

amsoil makes an equivalent made for nv4500s for only $13 per quart instead of 23 bucks a quart. i pressure cleaned the trans and its still dirty, im going to have to suit up in a rain coat and some mullet boots and spend an hour pressure cleaning this thing lol. for now, its short shift time...

got the trans cleaned, painted, put back together, and the short throw is done and works awesome. i already have a trans temp gauge in my truck so i welded a washer on one of the pto covers to add some thickness and tapped it for the sensor. i made my own tool to tighten up the 5th gear nut, i torqued it to 90ft lbs and welded it in 4 spits to the shaft. heres some pics





painted the pto covers with the same paint i did my rear diff cover with, hammer tone gray, i think it looks nice on a diff cover rather then just black and its subtle.

you can see the spacer for the shift tower i made, it ended up 1.028" tall, so its a major improvement.

Very nice progress, it looks like you reduced the throws by somewhere between 33% and 50%, thats a HUGE difference.

o man, it is nice. every time i walk outside i cant stop myself from walking over to the trans and bang some gears lol. i should be able to get through the gears in a hurry, probably not car like, but enough to wear i wont loose any 1/8 mile time compared to my auto.

im probably going to paint the bellhousing red. once you get all the parts in the truck, once everything is in the way and you can only see half of the parts anyway you just cant have too much red parts.

My stuff gets color coordinated for the particular vehicle, the suspension and other stuff on my Malibu either gets matching yellow or contrasting black, or neutral silver.

My suburban has been getting most everything in black, still along way off from the final idea getting started on it, that one is still up in the air.

I had a red truck that got black accents all over, another black truck that got lime green accents, and a blue truck that got a different shade of blue for accents.

all my freinds think im stupid for detailing out parts that are never going to be seen, but i think the details are the msot important, thats what makes the difference between a stock truck and one that youd be proud to show off. i got the new oil pan on, it looked red befor ei put it on so i didnt repaint it and now that its up agains my red block its got a bit of an orange tint to it, im a litle disapointed with that.

well iv got the transmission and transfer case in the truck, drive shafts are in, new oil pan, pump, rear main seal, the motor runs like **** but iv got oil pressure and no leeks and a service engine code so ill figure that out, its fueling issue. the truck is pretty much done besides a few issues iv got with the clutch line leaking, need a pigtail for the reverse light, ect.

iv got 2 big problems here, first of all, the 4 bolts that bolt the trans to the bellhousing feel pretty pathetic, one of them striped out after about 30ftlbs and the other 3 i cold only get to about 35 before they started feeling too sketchy. the bolts im using leave about an inch of threads in the bellhousing, is this not enough? how long are the factory ones, i dont have them? and why on earth is the torque spec 75 ftlbs in the service manual, iv never seen such a high spec for aluminum threads. im going to drive the truck as it is for now becasue iv got to drive slow to break the clutch in anyway but i need to take care of this problem, anyone got any ideas? i know ill helicoil the one, but the other 3, do i need longer bolts or is around 30ftlbs right?

problem #2, the switch on the transmission that tells the ecm what range you are in(the one towards the front) has a 2 wire hook up, the t-case that my truck had in it had a 3 wire. i think the difference may be that the automatic needs the 3rd wire for when the t-case is in low range where with a stick all you need to know is 2wd or 4wd so that it can send power to the front diff actuator. the problem is i dont know which 2 wires to keep and what to give up. my hanes manual shows nothing for it in any of the wiring diagrams. the 2 sensors could interchange, they are the same thread but one is longer, the one that came out of my old case sits probably a half inch deeper in the case then what i took out so i have a feeling it just wouldn't work, although i cant hardly believe anything inside the case would be different just to accommodate a different sensor. the case iv got is out of a 95 3/4 ton, my trucks a 95 half ton, the cases should be exactly alike, both np241c

alright, got some pics. heres how it sits as of now, yes thats the exhaust haning down, theyre 4" tips, you either love them or hate them lol. the diesel guys like em, everyone else says they are silly, the system sounds amazing, its got a more aggressive sound then open headers but it still shuts up quiet enough in overdrive. the sticker on the cab corner covers a rust hole:lol:

5" flomaster 30s

new oil pan and of course the nv4500

still need to bolt down the boot

and how my column ended up looking, its ok. if i come across the correct column cover ill buy it, but my home made little fiberglass insert piece works for now.
