96 xj sport 5.3 swap

sorry for no updates, life, any ways the exhaust is all finished went with a flowmaster 50 series and it sounds pretty good, great tone and not to loud which was exactly what i was after.

pulled it out of the garage today and went for a 10 mile or so cruise no faster than 45 since she still wont shift beyond 3rd(at least it feel like 3rd to me) and it takes some throttle feathering for it to do so at all. ill take it to a shop sometime this week (maybe if work is flexible enough) and let them throw a scanner on it to make sure the computer is comanding the shifts.
 
im going to take it to a shop and make sure the pcm is comanding the 1-2 shift and the 3-4 shift.

still debating weather i want to rebuild it myself, or have it rebuilt by someone
Repeated tranny failures is why I parted out my old XJ.

Lesson learned.
If you don't have a vast store house of tranny rebuild knowledge....pay a pro to do it.

exactly my feeling, I dont know a thing about them so i am very hesitant to try and rebuild it my self. I can get slightly upgraded/rebuilt unit for a decent price so i will likely do that if the trans is bad
 
ok, so its been a bit, works been out of control so i havent gotten a ton done, but i have gotten the exhaust all done, need to change an 02 sensor tho. today i spent a lot of time in the garage just cleening and organizing all my tools and parts since i have the jeep pulled out of the garage

im hoping to get some stuff done on the jeep tommoro, setting up the evap system. gonna drop the tank to install the tank pressure sensor, gonna pull the sending unit and extend the tank vent and probably put in the walboro 255 i have that i should have used in the first place im going to wire in the jeep fuel level sender into the GM pcm and hope it works even tho it wont be accurate

so after some digging ive learned that my transmission is actually a 4l65E, its got a 3KZD tag on it which is a designation for an 03 escalade with a 6.0...so score..(if it worked..) based on my research electronically they are the same as the 4l60e so the pcm should control it with out issue

i actually had the drive the jeep to work last week because the alternator in my jetta seized up and shredded the belt so that was fun, screaming down access road about 45mph in 2nd gear cause it refuses to shift :/ it was nice to drive it more than around the block no shifty aside the jeeps mostly been on the sidelines for about a year now since ive had a DD

also i relized today that the A/C compressor that came with my motor is seized up. bummer.
ive actually been toying with the idea of moving the battery to the cargo area and making a custom bracket to hole the factory jeep compressor so i can reuse all the factory lines and wiring in the "factory" jeep locations (aside from the triggers from the gm pcm) i like the idea of being able to pick up factory line from the parts store if something blow up instead of having custom lines.

or maybe using an r4 compressor and adapting the xj lines i think its compact enought to fit on the passenger side of the motor with out moving the battery

oh and the jeep speedo stop working, i thionk i either burned out the sensor its not getting the 5v reference from the phone charger board any more

sorry that got long winded, ill take some pics tommoro
 
pulled the tank today, got the evap sensor glued in place, extended the fuel tank vent, and mostly got the walboro 255lph pump mostly installed, just waiting on a new strainer and fill/vent hoses to come in





the walboro pump was nearly a direct replacement for the 96 pump, it a bit taller so i have to chop a bit off the feed hose for it to fit, sam plug and everything!




based on the go jeep site i should be looking at around 26 gallons with the vent mod.

still need to get a scanner on the jeep to make sure the pcm is doing its job commanding the shifts, if not ill look into trans options. thinking of doing a monster 4l60/4l65 thats good to 500 horse going to button up the engine bay and redo some wiring before i take it to a scanner
 
does any one see anything wrong with using the 5v referance for the egr as a 5v ref for the jeep speedo?

the 5.3 never came with it so in theory it should be an open chevy 5v that exists to use for it right? or am i nuts?

Be careful with the monster transmissions. I purchased their monster in a box kit and the way they do the reaction hub to front planetary Torrington bearing is bound to give people issues. I only found it because I rebuilt my trains, but after I called them they didn't seem to care much. I would hope that they address this in their complete units, but I wouldn't bank on it. My situation was converting a 4l60 to the 4l65 planets, among a ton of other upgrades, but you may be ok since you have a 65 already. Just a word of caution. I have pics and can provide you a couple links from LS1Tech if you want them.

thanks for the heads up, still not totaly sure what im going to do yet
 
got the speedo working! my phone charger 5v ref idea worked but it seems i damaged the resistor in it some how since it wasnt putting out 5v any more, but i stuck a pin in pin 48 i believe for the egr 5v ref (which my motor never had) and ran it to the 5v ref for the jeep vss and worked just fine.

got the fuel tank mounted back up, charcoal canister mounted, vent valve mounted, walboro 255 mounted in the tank with a new strainer( should have done this to begin with no mods at all were needed to fit it, plug was the same and everything) and new lines from the tank to the regulator

still gotta wire the evap stuff up and then im going to vigorously test all the wires to the trans
 
tested all the leads form the pcm to the trans connector, everything tested fine

switched upper rad hoses from the 90* elbows to a tweaked saturn hose( suggestion courtesy of racer32)

re did the intakes with a stubby filter from the parts store so the filter ends up behing the headlight

loomed nearly all the harness so the engine bay is pretty much wrapped up, aside from rigging a/c which isn't that important at the moment

going to test the internal trans harness tommorow

evap stuff is all done! seems to be working but i haven't really ran the jeep very long, no leaks at least.

Good job with the EVAP stuff. I ditched it but probably should have run it honestly.

Saturn upper hose... you mean rubber pretzel :) I looked through so many hoses and that is the only one I found that would fit my situation. Glad it worked :)

yea the 90* elbows were so stiff i had a hell of a time removing the hose, plus i wanted to get the intake tube a little lower. i kind of wish id stuck with a truck pump ant a passenger inlet radiator cause a universal hose would have worked great, the l99 pump just puts the inlet in an odd ball spot compared to the rad.

technicly in texas i have to run equivalent evap equipment that was installed on the jeep for its model year. plus i prefer not letting fuel i paid for evaporate into the air. san antonio doesnt do emissions checks but id rather have it installed incase they decide to do it before i can get street rod tags and be exempt from those silly little things.

just need to get the darn trans figured out, but man does it scoot at WOT! even if i can only go 30-45 ish in second haha

This X 1000.... If I did it all over again I'd buy the direct fit radiator and run a late model truck waterpump. The L99 one looks like it will be great but it ended up in a very bad orientation to the rad.

yup i thought using the l99 pump was a genius idea till the radiator was put in place lol.

there are so many things i would have done different, liiiike when i do a 97+ conversion with an ls swap on an mj some day..lol
