After turning up boost, adding a top mount intercooler, and turning up the fuel I could spin the tires on dry pavement around a corner when it shifted gears. My tranny has never shown any signs of problems.....after about 6 months of this I noticed if I gunned it off the line it would slip for a second when shifting gears rather than trying to spin the tires :). I promptly started easing off the throttle until after the shift......no problems since.

On the weekend I towed my travel trailer (recently lifted another few inches) back from osoyoos packed with family, bikes, canoe, skateboards, scooters and nerf guns :) I've always been able to keep the tranny temps around 210 f by pulling the hills in 2nd gear, 3000 rpm but in the hot weather with all the extra weight I hit 250 degrees through the slow moving hair pins on this side of princeton.

I have a big tranny cooler but I think for the hot weather I'm going to add another of equal size....

I wish there were a more cost effective fix than $2800 plus labour. Don't get me wrong I love my LC but I can't justify that much dough on a truck I could replace for $10k...

I was pulling 3000 rpm and 100kmh hour in 3rd out of Merrit, cruising along quite merrily until that damn light came on towards the top. Didn't think of dropping down to 2nd as it was pulling just fine. Same speed going up the snowshed hill on my way up with no issues, but it was a little cooler in ambient temperatures that day.
What is the $2800 you are referring to?
 
Hey Jeff- Are you not able to hold overdrive in 4th up the Coq through the sheds? I was able to do so last summer after the Intercooler install towing the 416 with a full load but I was doing about 80 kmh which it was holding with good EGT. I think I could have accelerated but I did not want to tempt fate...Trans temps were fine on this one...
 
I get a haze but not a smokescreen by any means whilst climbing.. Interesting as I figure we have similar trucks...
 
Well learn how to drive! And you are the one with the Pet Shop Boys hairdo...
 
With a few outfits doing crawler gears for the 80 series do any sets available have the option for a slight reduction in the straight through/high range gearing? I know that the 3.05 gears I put in my 60s Tcase also have a 8% reduction, allowing a 151 rpm increase in high range. Seems to me this would be a more useful option for a heavily laden rig, especially in off road situation.
 
I receiving some pricing for the Wholesale components via Pacesetter Products (whom I think used to be Outback Imports?) in the Yukon. They don't stock these items anymore but can order them in....

A442f billet torque converter $1900
Shipping $300 (no shipping if ordered with valve body below)
no core required

Extreme valve body $1290
Shipping $350 (includes shipping of core back to Oz)

= a whole 'lotta scratch

Hurry up and get your rig going Jeremy, want to hear some feedback on your significantly cheaper transmission results (yes, I know it's not apples to apples)
 
bit of a gamble ,but sounds like your going the v/b t/c only gamble anyway,why dont you get a t/c from roadrunner ( couple guys in town have used them and no complaints),then you can do the v/b later. contact longbow who knows maybe he will do one for you if your going to use it right away ,i know i would. i think longbow might get swampped pretty quick being he is one of those wild, wild fire techs and the busy season is comeing quick.
 
he is the mud member who did the v/b for wheelingnobb , i chatted with him breifly about getting more pressure out of the v/b ,sounds like a great guy but his tech was over my head . my buddy who does trannies locally got breifed by him on what to do. my buddy said he was the real deal with only a breif chat with him. but im waiting on the lock up mod to come out . maybe i should pm him to see if he is going to market this . if he is not then maybe he will breif my guy on what to do and i will either set you up with my buddy or i will get it done right away. my trannie is perfect but when i fuel it up to max its a slipping and shuderring. i did the t/c from tcs in langley it basically saved my transmission,but my clutch's are slipping from what i feel is not enough pressure,but the lockup in 3rd let alone 2nd is a must have in my books. you cant buy just the v/b gaskit kit you have to buy the whole kit apparently which gets costly doing it twice. oh and i had my stall lowerred, which was a huge mistake in my books.
 
My truck is finally moble and moving with its new heart. I got shipped away again for 5 week's with work but once I return I plan to get the last of the must do stuff done and fully test the V/B Don did for me. Mid to end of Aug you will have a review. The Roadrunner conver is workting great, my stall is right at 1600rpm and seems to work well with the low reving 4BD.
 
I was happy to get it running and out of the shop before I left. If I had a choice i would not be in this sh@t hole for 5 weeks trust me. The lock up works, I energized the solenoid and stalled the engine. I cant do any road tests till I get the last few must do things to make it road legal.
 
didnt mean to sound like that ,i meant it would be fustrating to not know if the lockup worked, being you just had to push the button in to see if it worked. ya i here you on the 5week crap hole thing. i spent much of my career living out of hotels and camps in the middle of bum pluck nowhere. excelent news on the lockup btw. wonder if it will work with a stock v/b , this could be the saving grace for the cruiser trannie heat issues . I can't wait for the real test.
 
The beginning of the end.

Coming home from Chilliwhack last night, just as I'm coming down 200th onto the bridge, it shifts really hard/weird after leaving a light and starts revving really high. It seems drive just disapeared and most of 3rd gear as well. Made it over the bridge in second, shifted to neutral and coasted down the offramp to my exit, then shifted back into drive which now seemed fine.

So no more wheeling trips this year until I can afford to repair the tranny, which is going to be awhile with home renovations getting first priority :(
 
That's not good.... bummer to hear that Jeff. Well, you could always drive one of your other LC's, :doh: never mind :bang:
 
Have you done the usual checks- just out of curiosity - is the oil burnt etc.?
