How many hours did it take? I’m assuming you had ramps? 2 sets of ramps or jacks with stands? Which way did you pull the old trans out?

There is a difference between something easy to fix and work on and something that's reliable. I came from the Subaru world before getting into Toyotas. Subies are like working on a car made out of legos. I can pull out an EJ25 in <3 hours solo. I know because I had to pull my EJ25 no less than 4 times in the 11 years I owned my Subie. Now that we are a 100% Toyota family, my engine hoist collects cobwebs.
I certainly had to up my DIYer game getting a GX. It is way more complicated (and way more expensive) to work on than a Subie. But, it's vastly better made and breaks far less frequently. And more importantly, I trust it.
Guess what I'm saying is, that if I had a 460 that was otherwise in great shape and needed a new transmission, I'd just bite the bullet on a $3500 Lexus reman transmission (plus a CSF radiator and aux cooler to keep it alive), which isn't much in the grand scheme of things.
I took my time. And it was tedious work crawling on back the whole time. Also did it myself with no help. So ~5-6 hours per day for maybe 10 days or so. So probably like 60 hours.
I also installed a transmission cooler and did the rear main seal while I was in there. So factor that in. Didn't have a whole lot of room to work with in my garage as I keep my cobra parked in there too.
If i did it again, I could probably do it in half the time.
I’m going through the parts and research now on what it involves. I rebuilt my LX450 engine, so I’m pretty sure I can do a trans swap. I do not want to be into this truck another $7K. I’m also debating fixing and immediately selling. Even with an add on cooler, can it reliably tow a 20ft boat? A Defender 90 will not. But a LX570 would. May just bite the bullet on a 100K mile 570. Looking at all the options that take this thing out of my driveway
Yeah, I feel the same way about pulling and reinstalling my LX450 engine. I think I could have it out in less than 3 hours after the first time. Hardest part was bellhousing bolts. 3-4 ft of extensions took care of that.
Would you recommend a transmission jack and how would you get the truck up if you had to do it again?
Yes, transmission jack is definitely needed. I would say an intermediate level of tools needed. And miscellaneous stuff.
10mm with flex head was useful for the stupid brackets on top.
Electric tools were good to have. Different socket types (deep/standard) of the same size with various extensions. Borescope helped for the brackets as well.
Small hands are a plus haha.
Where do you access the flex plate/flywheel bolts? If it’s through the starter, did you have to remove the exhaust manifold to pull the starter?
Yes,
-jack up car to lift all 4 wheels off ground
-Drain AT fluid from pan
-remove middle skid plate
-remove front/rear driveshafts
-remove mid section of exhaust
-remove passenger exhaust manifold
-remove starter
-unbolt TC from flywheel, put wrench on harmonic balancer bolt to keep engine from rotating
-place jack under transmission
-Remove center cross member
-tilt transmission down (maybe like 10 degrees at most)
-undo electrical harnesses (biggest PITA part)
-remove transmission bolts
-slide transmission out
-Unbolt Transfer case from old unit
Install is in reverse order
*Might be helpful to have the transfer ccaseput of the way when remove/install the electrical harnesses on top. Breather tube bracket can be accessed from passenger fender wells by remove O2 sensor bracket.
Might be missing some steps/order..
Thank you,
No problem. You can message me personally for any questions if they come up.Thank you,
Also, something i thought about is u need to remove the zerk fittings on driveshafts to get them to compress to get them out. Grease will ooze or shoot out. I used a 9/32 socket.
On the inside of the transmission, on the drivers side of the valve body, the linkage hooks up to a shift valve that is worked by an arm that runs along a stepped plate. The arm is not secured into a hole in the plate. Almost sounds like that is not connected.
We towed our 4,000# camper to Glacier and back this summer. I've also towed my compact tractor (about 5,800#) around here, and my buddy uses his GX460 to tow his 5,000# boat. So, yeah they'll tow just fine up to the 6,500# rating.
The LX570/LC200 used the same A760F your GX has until 2016 I think when they went to the 8 speed. As did all years of the 2nd gen Tundra (which are rated to tow far more than a GX460 is). The LX570/LC200 also have a UR engine that has the starter in a difficult spot, and there are reports of them having valley plate leaks like the 460 too. Other than beefier diffs, I don't see how they'd be any more reliable mechanically than a 460 is.
If you want to avoid the A760F, you need to get a 100 series or a GX470

Thanks for the details. Lot to consider to avoid this problem againWe towed our 4,000# camper to Glacier and back this summer. I've also towed my compact tractor (about 5,800#) around here, and my buddy uses his GX460 to tow his 5,000# boat. So, yeah they'll tow just fine up to the 6,500# rating.

First, can you even get a late 90's Defender in the U.S. legally? They're a rare bird here in CA. The ones I see are usually much earlier than that.
Also, as cool as Defenders (and Land Rovers) are, I can't get past their electrical issues.

LX570/LC200/Tundra/Sequoia they got AB60(F) which is the heavy duty version of A760. And my 2008 LX570 still got the p2714 problem after 220K miles.
I stand corrected! Bad internet sources it appears.
Do the LX570/LC200 lack an external trans cooler like the GX460?
Found this which seems interesting:
Not sure on the LC, but I know the LX570 has a small external cooler. I would assume the LC does as well.
