I only have 4 check balls, but there are 5 locations. Which do I use?
Expert:  Auto Go replied 5 years ago.

What year, make and model vehicle are we working on here?

Customer: replied 5 years ago.

It's a 1984 Chevrolet Custom Deluxe truck, but the engine and trans are not the original.

Expert:  Auto Go replied 5 years ago.

Do you know what the engine and transmission came out of? All information I have states that there should be 5 check balls in the TH350 transmission.

Customer: replied 5 years ago.
No I don't, but a seal kit that I bought for the trans is marked 1969-79 th350 and it comes with 4 check balls also.
Expert:  Auto Go replied 5 years ago.
ok, well, that is all the info I have. I will opt out and if any other expert has any more info they will post here. Thanks.

Hi, glad to be of help. graphic

69-79 only used 4.

number 5 is for lockup on later models

number 2 needs to be in there.no matter what.

number 3,4,1 dont need to be there they to cushion the 1-2 and 2-3 shifts. If left out it will give you harder shifts
