First time Attex owner needs help with rebuild.

I would change those T pins as they will not get any better with time.
Buy oversize hardened dowel pins, .002 over, McMaster-Carr has them, and a reamer to get an interference fit.
Press them in, not hammer in.

The T shaped pin in the pic above fits loosely in the hole. Do you think that's the reason it will not engage reverse? The hole measures 0.25 inches in diameter and the pin measures 0.24 inches diameter.

The T-pins had to be able to rotate as the shifter moved and that is why they have clearance. replace with a round pin that has a tight interference fit

Thanks for the advice everyone. With the shifting levers removed I got the transmission to go into reverse with a screwdriver. So i made a replacement pin for the left side and put it back together and IT WORKS!!! Again thank you guys for all the great advice.

The next thing i need to do is fix the holes and small cracks in the tub. What's the best way to repair the plastic in these old machines? What kind of plastic is it?

The older brittle bodies are ABS and can be repaired with ABS melted into a goo with acetone and reinforced with cloth.....Or with special epoxy, and cloth makes that easier too.
The HDPE (high density polyethylene) was used in the newer bodies more mid to late 70's.....That is better repaired with the epoxy. I've had mixed results with plastic welding.

I seen that G/flex and was wondering if it was any good? Also anyone know where to get the axle gaskets for my Attex chief?

You want it? i think it would work if it was the right size. It has more contact area with the channel. it seems like a good idea in theory.

The epoxy holds up very well, just remember to follow all mfgr recomendations on prep. Clean, scratch, alcohol clean and flame treat prior to application and it will adhere well. Every material has it's limits on flexing and something caused the cracks/holes to begin with so reinforce as needed. The beauty of epoxy is 2 dissimilar materials can be adhered together. You could use sheet aluminum or HDPE as patch material.
