1HZ - rear transmission mount (1 Viewer)

[ATL Cruiser]

I've come to the conclusion that a rear trans mount does not exist for my 1992 HZJ77 automatic.

Here's what it looks like:

Has anyone ever seen this mount? I can confirm that it is NOT any of the following mounts:
12371-58060
12371-58010
12371-58021
12371-61020
12371-61031
12371-17010
12371-68041

My closest guess is this mount: 12371-17080. The end edges are different.

12371-17020 is the correct part number and that's discontinued.

12371-17080 is for an R151F manual transmission but it might work. Buy one and see.

I would look at 12371-17110 as a possible option.

Thank you. Just ordered from UAE. I will update once it's in hand and I've got it (hopefully) installed.

After waiting almost a month, the 12371-17080 arrived. It is close, but off by 15mm.

I did look hard for 12371-17110. It shows as NLA everywhere, and I cannot even find a photo of it.

Hoping someone here has some clever advice before I break out the welder and start modifying these mounts to fit right.

Opportune time for a manual transmission swap.

OGB speakers the truth, you need a brand new r151 for that thang.

For anyone interested (i.e. all 8 people that own an automatic HZJ77), I finally resolved this.

Cruiser Outfitters (@cruiseroutfit) helped measure a bunch of their inventory. I'm grateful to them.

12371-58060 - does not fit
12371-58010 - Cruiser Outfitters measured no
12371-58021 - Cruiser Outfitters measured no
12371-58031 (EGM58030R) - Cruiser Outfitters (NLA)
12371-61020 - Cruiser Outfitters measured no
12371-61030 - Cruiser Outfitters measured no
12371-61031 - does not fit
12371-17010 - for manual HZJ77
12371-17020 - for automatic HZJ77 (NLA)
12371-17080 - close fit
12371-17110 - NLA
12371-67030 - does not fit
12371-68050 - does not fit
12371-68051 - maybe
12371-61041 (EGM61041R) - fits with offset

I found an old post from Kurt referencing the same issue.
' BJ74 engine mount - https://forum.ih8mud.com/threads/bj74-engine-mount.858487/page-2#post-11099841

Using that information, I tracked down a 12371-61041 (Cruiser Outfitters EGM61041R), and it fit great:

Had to oval out the cross-member points a bit, and it fit perfectly.

It's amazing what fresh mounts do on a 30yo truck. We fix them for customers all the time, but it's been awhile since I've swapped motor/trans mounts on my own vehicle. It's like driving a new car.

Glad you were able to find an option. Did you use the 68041R or the 61041R? That sure looks like the 61041R

You are 100% correct. I had a typo in my mega-mount spreadsheet. Fixed.

Thank you again. Cruiser Outfitters saved the day on this one.

That is dedication to solving a problem. Well done.
