Needed: Speedometer Driven Gear to case Retainer for TH350


Slowly getting things back together and can't find this little part to allow me to attach the speedometer cable to the transmission.

It's the retainer which is #19 in the diagram. Also need the bolt, #20, but could always improvise as its a standard size and thread.

It's the retainer which holds this part in place

Anyone got a spare they can spare?

Thanks, Ted

There are two different sizes one is a little wider than 2" and the other smaller one is 1 7/8". You will have to measure the diameter of the hole in your transmission. I searched pic a part all winter in florida for these retainers and only found one. It was the larger one out of a full size mid 70's buick. There are a wanted item as the plastic ones just break apart when trying to remove them.

Those look the same as a Saginaw miuncie powerglide t10? Whats the measurement for the part? I know you have them but it would be good to have this on record for future needs?

The one in the drawing is also used on buick, olds americian Pontiac with turbo 350 and are a large diameter. Turbo 400 are the smaller diameter. Chevrolet turbo 350 , powerglide used the small retainer which is very common. The horseshoe style retainers are reproduced and are not cheap. We used this style retainers when we swap out the plastic style retainers used on 700r4 transmissions.
