I've been putting this off for years. I attacked it 2 weeks ago.
Dropped front tailshaft.
Disconnected exhaust near rear of gearbox. (Is aftermarket so not sure about factory one)
Disconnected auto shifter linkage.
Unbolt gearbox cross member from chassis and lower box about 6".
This allows access up the sides of the box to the 4 bolts.
Pop the little linkage clip and pop the arm out. Small clip, washer and plastic bush will slide off. Don't loose them.
Undo 4 bolts. Need a 1/2" ratchet to crack the bolts loose.
Shifter will jigsaw up through the floorpan.
Mr Toyota had a shocker... steel shaft through alloy housing. Oxidisation galore.
My 105 GXL had a roll pin holding the handle to the shaft. But the 100 looks to have a circlip on the other end in your picture. Looks easier. Roll pin was hidden in the boot. Pain in the bum.
You'll have to punch the shaft out of the housing. And i mean it'll be stuck.
I thought about rebushing the housing, but decided to just clean and grease.
I buffed the shaft to give it a little bit of clearance.
I filled the cavity on the top of the gearbox with grease. Filled the top housing with grease.
Reassembled.
It took me about 6hrs fumbling my way along. Would be easier with an assistant to pass tools, work jack etc.
I didn't find anything wrong with any of the linkages.
Worked perfectly after that.
Took our camper to Yalwal and flexed it all up. So nice to have fixed it.
