I purchased this 01 24v about 2 years ago and the previous owner said that he had a local diesel performance shop put in a FASS, Billet flex plate, and a triple disk torque converter. I'm not having any issues with slipping or anything, when the transmission shifts it's firm and grabs the gears instantly. While I was under the truck doing the oil change I decided to take off the inspection plate and just take a peak. I was wondering if anybody could tell me if this TC and Flex plate look stock or aftermarket.

 

I've tried looking at a bunch of different torque converters to try to match the color but I can't seem to find anything, and as far as the quick and firm shifts, what are the chances for it having an upgraded valve body? I just wanted to make sure before getting a Quadzilla (Mostly for monitoring right now since I can't confirm the drivetrain). Not looking to go crazy or anything for power right now, I'd just like to know for future reference for later when power adders fit into the picture. (Currently working on getting all the steering and suspension dialed in). Any input would be grateful, I'm sure I'll know for sure when I pull everything apart to do the rear main and build the trans later on when I graduate school.

Need to just talk to @Dynamic.

 

I've had my 1996 Dodge 1500 upgraded on Dynamic design and it works awesome. Then @IBMobile was here and I was driving his truck and wow! With full lock up through the gear that truck is just flat mean with 4.10 gears and 245's tires.  Really firm shift and everything. I'm sure Dan said it was a Stage 2 kit in his transmission. My is a modified stage 1 on my V8 gasser.

Sounds like fun, One thing I forgot to mention is that I was doing some research and some people were saying TC lockup should only happen in OD with a stock valve body but mine locks up at exactly 40mph in third under acceleration.
I’ll definitely have to check it when I replace the transmission filter. Going through all the fluids since owning the truck, got the front and rear diff and trans fluid to replace. Hopefully new fluid stops this rear end from popping on sharp turns and low speeds. Going to have to remember to check IBMobile’s setup. 

Sounds like you have a limited slip rear end. Be sure and add the additional lubricant when changing. That is likely to be source of the "popping " you are hearing. Wish I could with the trans but thats above my pay grade.

Yeah that’s what I was thinking too. I will have to look up the VIN soon and check, no tag on the diff cover. Will have to do it as soon as I get the extra funds, it’s like $100 in fluid per diff.

My 02 has a tag in the glove box the identifies mine as such. You can also jack the rear off the ground and spin one wheel. if the other turns the opposite direction it is an open diff, if it spins the same direction, limited slip. What kind of oil are putting in them. I spent no where hear that much for both.

A stock valve body will allow lock up in 3rd and overdrive like you explain .a modified VB will allow lock up in 2nd.

From was I was looking up royal purple with the friction modifier is what people like to run. But it’s like $18 a quart

Friction modifier will sort the rear end out, I use Caterpillar stuff in mine  https://parts.cat.com/en/catcorp/1U-9891  doesn't need much at all

I have run nothing but dino oil in mine. Not knocking the Purple just to pricey for me.

While I do tow heavy I do not tow alot maybe 4k to 5k miles a year.

$18 a quart woud explain the cost. I think the dino is about $18 gallon.
