Fishroe 261 #1 Posted March 8, 2022 I know the manual says straight 90 but I had this leftover 414-8 It is gl-5 6 Share this post Link to post Share on other sites
ebinmaine 67,593 #2 Posted March 8, 2022 GL 4 and 5 have different qualities. I believe you're ok either way with a Horse transmission because there's no brass/other yellow metals. 4 Share this post Link to post Share on other sites

kpinnc 12,083 #4 Posted March 8, 2022 You'll be fine using that oil. Half the tranny's I see have muddy water as lube. Be sure to put on a new shifter boot. 7 Share this post Link to post Share on other sites

The GL5 is much softer on copper then GL5 was when it just came out 2 Share this post Link to post Share on other sites

None of those had any non-steel metal that I was aware of. Is this something that started later or is that some sort of coated alloy that appears silver? Not a big deal one way or the other I guess. I'm just curious. 2 Share this post Link to post Share on other sites

I'm just curious. Bushing shows up in 8 speeds, 4 speeds and the 5053 trannies basically all modern (not 3 piece units). Now on the other hand the cheap GL5 I use from Wally world says it protects against corrosion of copper or bronze bushings 2 1 Share this post Link to post Share on other sites

I'm just curious. Like @pfrederi 's imago shows, number 43 is a bronze bushing. The picture of my tranny is that from my 1974 Wheel Horse raider10. If I am not mistaking. Didn't notice it at first either. But that's all their is of 4 hours ago, ebinmaine said: brass/other yellow metals. In WH tranny's 2 Share this post Link to post Share on other sites
