Transgo Install Pics
 

Alright, got everything in and running.. finally..We got a late start thursday night and ended up working pretty late into the night. Well, we got everything put together and backed it out of the shop, reverse acted funny, had to rev to get it to engage. down the road, 1st, 2nd, 3rd... no 4th/OD .. so i take it to a little wot. Hits second as usual (harder obviously) and second runs to 100 and i shut it down.. now no 3rd.. i'm sick at this point... take it back to the shop, swap out to the old computer (had nelson send a retune) thinking maybe it was a tuning glitch. Same thing. So off to the house i go... Thinking about every step and knowing that i read every step at least twice (measure twice cut once) kind of thing. and it hits me, i remembered seeing a plate Under the springs and stuff in the transgo box. I whip a shitty, head back to kevins house, open the box, take out the black piece that holds all the shit, and sure nuff, theres still that little plate. It goes between the manifold pressure switch and the valve body. and covers the pan side of the 2-3 3-4 solenoids. So today we get it back in the air, pull the pan, the switch, and the valve body just to give everything a once over. Look at the seperator plate; and one of the block offs that you put in the seperator and chamfer had come out and was nowhere to be seen.. pulled the filter out of the drain pan and that little SOB was sittin on top of the filter. We flattened it out, and reinstalled it this time making damn sure that it wouldn't come out. put everything back together, added the fluid, put the new tune in and off we went! slowly down the road, 1st, 2nd, 3rd, 4th, OD... wooohooo!!! Everything is working fine now!! Couldn't be more happy with the kit!! Below are some pics .. couldn't take alot cause my hands were covered in fluid the whole time!!

looks good, Congrats! took me 3 days to do mine, but I am slow, lol.

yea, it took us a while, including a pit stop to Krystals!!! Really wasn't that bad of an install, just tedious, if that's the right word!

Congrats and nice you got your problem figured our and fixed easily. Well maybe not all that easy. Drip drip drip.... :jest:

What size did you drill the holes in the separator plate for shift firmness? How do the shifts feel?

One of these days I will get around to doing mine. :)

:cheers:

still haven't done yours with all that gutter power? :bang: :jest:

LOL :jest: No but the shifts do feel a little soft and wishy washy at 10 psi so maybe I oughta get my round-to-it. :eek2:

shift firmness is something i was real ticked about.. the kit came with 4 drill bits, a .120, .086, 3/16, and .055. The instructions said there are 4 different sizes i could do, soft=.076, average=.086, and firm=.096, and race only of .120... well.. the kit didn't come with a .096... and i didn't want to do race only... i tried for an hour or better to find a .096 and it was too late to call tech assistance.. i ended up going with 'average' so i'm not happy about that. but, it still shifts hard! the 1-2 is abotu the same (maybe a bit harder) than my old nelson tune with the line pressure way up, but the 2-3 is totally different, it slams the 2-3 at around 98mph, haven't had it in long enough to do a wot 3-4 run, will soon though. Under light acceleration around town, before it acted normal not really shifting any different than stock, after the install, it shifts firm and clean through out the gears, even goin into OD feels firm!

I'm happy with it, when i go back in at some point i'll redo to the larger "firm" size hole in the seperator plate!

I have the .096 holes, but the next time I'm in there I'm going to a .120 3-4 hole as the .096 is to soft for me WOT

Did you get Nelson to send you a new tune? What did you have him change?

I asked Westers and he said due to the adaptive nature of the 4L80E to just go ahead and do it. I will try it and if it does not seem to be working as I think it should I will get him to adjust it.

Mine came with a 3/16, .120, .086 and .055. I never thought that it would not include all the bits. Thanks for the heads up on that.

Yea, i had nelson retune it for the transgo along with raising the 1-2 and 2-3 shift RPM, he said that i shouldn't put the kit in with the current tune cause the line pressure was so high already! Yea, if i had known about it not having all the bits, i'd have definately got them prior to starting the install.

Grippy - where'd you get a .096 bit and what speed do you figure your WOT 3-4 shift is at speed wise?

Out of my 154pc drill box :judge:

:bang:

Of course! Where else would one find a .096 drill bit. :jest:

I get letter, number and decimal drill bits from a local industrial supply house.

Or you could buy a 154 pc drill set. Or I could borrow one from my neighbor who has a 154 pc drill set. :jest:

Do you suppose you could use a bit that was close rather than the exact size?

3/32" = 0.09375

I will contact Westers again too just to double check. :)

Bringing this back from the dead. I am about to go in and re-do my seperator plate. I dont know what the first owner set the hole size to but, 1-2 is a neck snapper at 20mph and light throttle. Only the 1-2 shift, others seem fine.

If I drop to the soft setting on my new plate will it effect the wot shifts as well? I thought line pressure increased with rpm? I think the plate is drilled to .096 right now. Its an 80E with a 2600 Vig converter, in the Tahoe.

So who runs at the.076 setting and likes it?

I personally think that you should put a pressure gauge on it first before you do anything. But what do I know? :chug:

What are you, some kind of transmission guru?:eyes:

How the hell do I do a pressure check?

Get yourself a 300psi gauge and connect it to the pressure port above the shifter linkage. I would like to know what the pressure is at the different throttle angles before going inside of the trans. I am concerned that your pressures might be at max line. Is the 1-2 shift the only one that is hard?

The 1-2 is the only one that is harsh. The others are firm but not overly firm. They feel like the trans you built for me. The 1-2 is good as well when I'm really on it but the part throttle low speed is like a whip.

When the truck has sat overnight and I first take off the 1st 1-2 shift of the day is pretty soft, like the fluid is colder and that is making a difference. Then 30 seconds later its hard again.

I will get the gauge and try to get some numbers. You want just low throttle or do you want some runs with a little gitty up to compare it to?
Will TPS% associated with a psi work?

I had this issue with mine the last time I rebuilt it. I dropped the 1-2 shift pressures by a "small" percentage (don't remember exactly what) from stock settings. It's a "little" softer, but you know something was done to the trans b/c it's still somewhat firm. I'm hestitant to go any further without knowing actual pressure across the board. 2-3 shift is pretty firm too. 3-4 seems LAZY-soft. Lockup is nicely noticeable. :judge:

BTW, .096 bit was used to drill out recommended holes in the sep plate.

are there any washers in the accumulator piston?

Good question... never thought about that. :hail:

Dear me- I'm gonna hafta drill now, too. I think I'll give this one to the shop.............

I thought only 6oE used washers? Not sure. I didnt install the kit so I dont know what was done.

they do, looks just like this

I remember OH SO WELL what those look like... :judge:

Spent MORE than my share of DESIRED time inside a 4L60E. Fortunately, it's holding up! :drive: I'll go knock on wood now... then pray to the trans gods to let the stars stay aligned. :hail: :lol:

Is there a big difference in shifts with this kit combined with servos? Dont want anything too harsh but I dont want to break my trans.

Pressure readings:

P/N/D 65psi

As soon as I give it some gas it goes to 150psi. Then right before the shift it drops back to the 65psi range and then pops right back to 150psi and the shift happens. I did this several times to make sure it wasnt a fluke.

That sounds like something that would happen to me.

I actually think this may be correct/normal. I know the idle pressure is good and I'm pretty sure 150psi is about right. I would think the trans would drop pressure right before a shift to make it easier for bands/clutches etc to release and then quickly bring it back up to apply the same bands/clutches. I think 180-200psi is max pressure but it may be more.

Also forgot to mention, reverse is 100psi.

Are you giving it minimal throttle? Also what rpm's are we talking about with these readings?

Less than 20% TPS and less than 2000rpm. I will get the TranX on there and get you some info.

I'm assuming that the psi is at 150 at that throttle. You let me know HOE! Remember green bottles for Xmas! :cheers:

Correct, 150psi as soon as I touched the throttle. If I got on it a little it would see 180psi. My luck is the installer drilled the plate to .120:turd:

Maybe the checkball is missing. The intermediate clutch feed circuit (used for 1-2) is the most likely to jam the checkball into the separator plate and get it stuck, so maybe the installer just decided to take the easy way out and avoid the posibility entirely.
For what it's worth, the intermediate and direct circuits on mine are drilled to .096" and overdrive is .120". That comes out too harsh at low throttle for the 1-2 and 2-3 so I tuned down pressures for those at low throttle. This has two benefits: It helps prevent the checkballs from oblonging the holes in the separator plate and it makes for snappier downshifts since there's less pressure to bleed off and larger exhaust passage (checkball hole + feed orifice).
