is there a how to on changing the m/t fluid for the lsj? is it just me or this is supposed to be ridiculously easy, anyone done it? and what's the best manual tranny fluid out there for the lsj, GM recommended or Royal Purple?

...thanx

 

never done it but i hear it's a PITA!

 

There is a "How to", I used the GM recommended fluid. The hardest thing to do was get the the drain and fill plugs off. If you do a search it should explain how.

Edit here is a good link

that's for the F23...there's no how to's for the lsj transmission

 

I just did mine, i was super simple. Take off your drivers side tire. You will have a clear view of you tranny. Going over the rear side of the control arm you will see a screw that accepts an allen key, that will be the fill plug. Go almost directly under it and you will find the drain plug. The only thing that is a PITA about it is you need to find a rather flexible funnel to put fluid in.

 

It is the same instructions to do,, just take off the left front wheel ans you will see the two allen screws. One is placed next to the subframe and the other one just above it

 

thanx...which tranny fluid did you use and how much did it take?? royal purple? or something else

 

I ended up using the gm fluid to be on the safe side. You need 2 bottles of it. The manual has the part number and exactly how much is needed.

 

just use royal purple ATF. ive done mine both times i broke an axle. its easy

 

1.8 quarts of gm fluid or 75w 90

 

75W-90 Royal Purple Max Gear Oil, not ATF!!!

 

I'm wondering if Royal purple will help quiet down these noise makers . Anyone notice any change in that area?

 

you can use ATF, i researched it

 

Could you please enlighten me on this research. I used the 75w90 max gear oil and I would like to know the differance and your sources of research. Thanks...

 

i dont remember exactly where i got it from, used the owners manual to see what it suggested and it turned oiut to be nearly identical **** to the RP ATF

 

the part number fluid in the manual is a gl 4 gear oil which is equivalent to 75w 90

 

beat me too it. if you don't take the tire off then its a pain to do.

 

how important is it to put the loctite 520 thread sealant on the drain plugs? can i just do without it for now? are there any other alternatives that i can purchase at a local parts store?
