My current project

they should have somthing that would replace the 4l60e. the 4l60 should be a elec version of the 700r4. it would be cool, then my 1500 could do some towing.

just put a 4L80 or 4L80E which ever you need you won't break an 80 towing your 1500 can't pull more than the 80 will handle.
 
Ferm and I, well our diesels have the 4L80 in them, that's a strong trans, they were rated at able to handle 1000 hp and 1200 ft tq.
 
nope that 80 is a larger case and all totally different pan and carrier set up

look at the junk yards for a 2500 Suburban with a 454 BBC or 6.5TD also a 2500 to 3500 GM truck with either the 454 or the 6.5TD has them in them

yeah thats what it looks like i need to get, is there anyway to build a 4l60e to handle what a 80 can?

A max build on a 4L60E can take just about the same as a stock 4L80E. A shift kit in the 80 though and you are WAY ahead of what a 60 can even think about. The 60E can be a decent tranny for a small block, but requires some work to get it there. A TRANSGO HD-2 shift kit, HUGE tranny cooler, ALTO clutches except for the 3-4 pack(the Z-pack is the way to go there), heavy sprag and one way clutch stator, 10 or 13 vane pump, corvette servo or SONNAX billet servo's(even better, but shift HARD!), SONNAX 1-2 shift valve, deep tranny pan, and a SUNCOAST billet converter will get you a stout 4L60E. You'll be looking at around $1300-1500 worth the parts alone though. Depending upon the year of your truck, an 80 will most likely be easier to swap and be less money.

yeah thats what its looking like, im findind 80's for about 600-700 on the net from the parts finder site i got my 60 from. i sure i can unload one of te 60's at least half the cost of the 80.
 
no problems anymore since i put the new trans in. but its a 97 k1500 w/ the 5.7
how it all started was the truck was for the dealership where i work that the boss would drive to and from his house and we would use it sometimes to pull boats to the launch to run. at 90k miles the transmission went, i think the sun shell broke at where the splined collar is welded to it or so what the trans guy said. well he rebuilt it and 30k later it was making noise in just rev/1st then on the way to work i lost OD and then i lost all forward gears and reverse would work but go out. when i tow the v-20 its 80 miles one way.
 
Sun shell failure is unfortunately common, but the BEAST sun shell takes care of that. ANY 4L60E build(and 700R's) should include a BEAST, it's the best $60 you can spend on one. If your running a stock 97 with even a 350 in it, a 4L60E should be plenty. Put a bigger cooler on it, TRANSGO HD-2 shift kit, 1-2 shift valve in the valve body while your there, and swap out the 2nd servo with a corvette servo while doing the kit as well. That will get you ALOT more holding power. Also reducing tranny temps and keeping them under 200 will make it live a happy life, anything higher and they don't last.
 
you would have thought that the guy would have at least installed the beast, but after i spoke with him he seems a little shady. i bought the dvd and atsg's manual for the 4l60e. thanks for the tips on beefing up rebuild. this summer i'll probably rebuild the one i removed with all the mods and wait for the new one to go out but i definately need to install and temp guage. also ferm i have a trans cooler and its kinda big, but how big of one should i run?
 
The factory one is pretty good if it has the optional towing one. GM ran the 11" wide by 4" tall one on some and a 6" tall on others. The problem I have seen though is the way GM mounted it. The inlet and outlet are both on the bottom, and I have seen them get slightly plugged and not flow through but the bottom 2 or 3 rows on the cooler. I rotate em 90 degrees and feed it through the bottom and out through the top, this way you know that you are using all of the coolers passages. I like this cooler as an easy add on one as it comes with line and adapters to hook right to the radiator. You could even hook it up along with your current one for extra cooling.

hmmm...my cooler is about that size of the summit one. i removed my grill and was inspecting it i can put a tape on it tonight to see ,but it was quite large. it pretty much filled up the left side of the radiator with a little room up a the top. i think ultimately i need a temp guage to keep the temps in check.
 
now that we are on the subject, what would be involved in swaping out a 60e to a 80e in my 99 1500 Suburban. Its got 175k on it, I've changed the fluid on a regular basis. We bought it with 80 on it, so I don't know if the transmission was done before we bought it or not. We live in flat land and I've rarely towed anything with it(that may change). I figure when it hits 200, I'll start on the fresh block I have in the garage( have a fresh set of vortecs as well), I'll probably throw a little cam in it, with some good valve train, but otherwise leave it pretty tame. I might as well take care of the tranny while I'm at it, and I like the idea of towing in OD. I want the computer to work well with everything
 
99 is a fairly easy swap really. The tranny bolts right up to the block, but the input shaft in the transfer case is different as a 60 uses a 27 spline output and an 80 uses a 32 spline shaft. You do have to change a couple of the pins in the trans plug, and I believe you have to run one wire from the PCM to the tranny. Then you have to have a 2500 program flashed into the ECM for one with a 4L80E as one of the solonoids in the 80 works backwards from the 60 as well as the gear ratios are considerably different between the 2.
 
Back on topic.

Been a slow couple of days lately. I had to go run errands MONDAY, so I only got the oil pan back on it after putting JB weld over the seems for insurance. Went out today and built a stand for the engine and an adapter to put the tranny on my engine stand to make it easier to work on. Unfortunately I had a mishap today and broke my wiper motor cover and housing when the studs for the glow plug controller caught it when the engine swung sideways on me coming out

. Fortunately I priced out an aftermarket one for $68, so at least it wasn't TOO expensive.

Here's the oil pan epoxied over at the seems and everywhere that I had taken the paint off.


The engine sitting on it's stand.


And the ALLISON on the engine stand.


And my mishap.


Sure is empty looking without the powerplant.
 
Interesting note about the beast sun shell. I went through four different 700R4 rebuilds (Not by me..) for what turn out to a problem related to the sunshell. The Beast comes with a small washer that MUST be installed or else you'll be swapping out the tyranny in no time for another one. Just ask the guy who keep rebuild mine over and over and over.... Worked great after he finally figure out it was just a extra part...:oh:
