Shifter Pins

77 Cj5 Ŧ-176 Dana-300, 302 V8

I need to replace my shifter pens, I bought some the other day. The new ones are bigger, is that normal? How do you install?

You machine the holes out to fit the new pins. They make replacements larger because it is common for the pins to loosen up in the housing making the holes oversized. You want the pins to have an interference fit so they have to be pressed in.

 

What is the best way to go about that? Drill them out?

 

I replaced the pin, I tried to use a C clamp but I didn’t have one a small enough . I used a mini sledge and tapped it in. Lubed it before hand.

Should I replace the other side while I’m at this point, it hasn’t fallen out yet, but is worn down?

is there any other routine maintenance I should do at the is point?

Does anyone have a good link to the process of flushing & replacing transmission fluid?

Thanks again for all of y’all’s help!

There's not really a good way to "flush" and manual trans. If you are worried, a few drain and refill cycles with a little bit of driving in between should do it.
My preferred tool is the outboard motor gear oil pump they sell at Walmart

also, not sure about the T176, but the older transes like GL4 gear oil, and sometimes have issues with harder shifting when filled with GL5

 

Look in an '80 or newer TSM at the last page of the section about the T-176 for info about lubrication. My '82 TSM specifies 85W90 GL5 gear oil for the T-176. GL5 is the generic gear oil you can buy in gallon jugs at WalMart and elsewhere.

To change the oil, there is a fill and a drain plug. Pull the drain plug and let the oil drain out. Put the plug back, remove the fill plug and fill with oil to the level of the plug. Put the plug back. Done.

Since the GL5 oil is inexpensive, I would definitely follow the above suggestion and change the oil a couple of times if I wanted to "flush" the transmission. Gear oil like this should be replaced when the transmission is serviced, or if the oil becomes contaminated with water. There's typically no official specification for changing or flushing the transmission - just use common sense.

A Dana 300 probably does not share oil with the transmission - this is something you could look up in the '80-or-newer TSM. This is not the right transmission and transfer case for a '77, so you will need to refer to a different year TSM for these parts.

 

Also, it never hurts to be reminded to pull the fill plug first before draining.
