• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Built 4t65e - The results are in.

Begin original post:

This fall/winter, I'm planning on building a transmission for my car.

Here's what I'm planning on using for parts:
PNH Torque convertor
Master rebuild kit
-New frictions, steels, seals, gaskets, and filter
All bands
Bonded spacer plate
Torlon check balls
Oversize 2nd steel plates x2
Molded 2nd apply piston
Molded 3rd apply piston
TEP reconditioned reaction carrier - Original is out of spec
300m iput shaft
7/8" 2.93 single chain set
Borg warner PCS
Borg warner TCCS
AC Delco shift solenoid x2
Superior AFL valve repair kit
Superior valve body kit
Sonnax TCC relief valve
Trans-go shift kit
Dorman pan w/ drain plug - Junkyard poked the original
Hardened 4th clutch hub
Differential lube tube clamp
Lube dam
Round magnet

Here's the "mods" I plan to do:
Tightened 2nd clutch pack
Tightened 3rd clutch pack
Convert to internal cooler check ball

Here's what I'm debating:
Bushings - Not seeing any substantial wear on the originals
Drive sprocket bearing - Feels tight, but I'm told it's a common failure (?)
Bonded sonnax 3rd apply piston - Because I'm right there

The core transmission was pulled from a smashed junkyard '02 Regal with an unknown history. The only thing I know for sure is, 4th gear was gone (based on the completely absent splines on the 4th hub). No chunks in the pan, average amount of sludge on the magnet. Fluid looked.... average for a Tucson w-body. No burned or scarred internals.

This setup is probably overkill for my current, or even future mods, but here's my though process: I'm going to pull and shelf my current stock, working transmission. Install the built trans and roll on that until I eventually move on from this car. At that point, I'll re-install the stock trans and sell the built trans as a low mile working unit. Hopefully for what I have into it.

For what it's worth, I have all the time in the world to do this build. No rush on anything. I also have HP tuners, so I can make adjustments in the PCM to take advantage of all the improvements in this build.

So what do you guys think? Is it a solid plan? What are your thoughts on the pieces I'm debating?

Thanks Bill! What are your thoughts on replacing the bushings? Old ones don't show any odd or excessive wear.

If the bushings look good don't worry about them. Caged needle bearing in the stator support I always replace because it is a very common failure.
 
Re: Fall transmission build - Opinions welcomed

If everything else is overkill, why not replace them anyways ?

I think this is the part that always seems to broken for me on my first couple of builds

Is there a way to get the old one out without having the special Kent Moore tool? How do you remove it?

Only because I've never replaced them before. I don't know what kind of tooling it would take. Ebay bushing/bearing puller and Harbor Freight arbor press?
 
Re: Fall transmission build - Opinions welcomed

Pull the TC seal and the 3-4 torx screws are right there. Poof.. done.
 
Re: Fall transmission build - Opinions welcomed

I guess I don't understand Bill. That gets the stator support out of the case, but I still need to get the bearing out of the stator support.
 
Re: Fall transmission build - Opinions welcomed

at least I'm remembering it as one piece. Unless I just pulled the bearing and replaced it.
 


Re: Fall transmission build - Opinions welcomed

Yeah. Definitely 2 pieces. Caged bearing is pressed into the stator support.

Re: Fall transmission build - Opinions welcomed

I used something else to get it out.. Might own that tool now. Wanna buy more 4T65 tools?
 


Re: Fall transmission build - Opinions welcomed

I don't recommend the PNH torque converter at all. While mine hasnt failed or had any issues to speak of, its very, very loose, which makes it horrific on the LS4. My gas mileage dropped to 12.8mpg on this converter as it constantly has to rev to about 2500rpm to accelerate at any good clip. It stalls around 2800 and flashs just above 3k, while it may be ideal for the cam I have, it makes the car feel like a tug boat in the low end. I've spoken with dave at TEP about this and he said its typical of the reman JTFM converters, as they are built around the GTP's 3800 v6. I also spoke with several LS cam mfg'ers and they all recommend getting a custom converter like a circle d, which said they would be more then happy to do the 4t65e. It would be much tighter around town and you could still probably get the stall you wanted without having to worry about it feeling "loose". I'm looking at doing this in a few months and having it swapped out.
 
Re: Fall transmission build - Opinions welcomed

Get a PI reman converter through Dave at TEP. I'm like stock stall speed or even lower. 500whp+ Whipple car is running a 2500 stall.
