I was changing my trans. fluid & filter today --- and noticed the one bolt that holds on the filter to the valve body, after torqueing it to specs ( 10 ft. lbs ) that it had some slack, like it was missing a spacer or washer. The replacement filter ( Autozone TF 206 ) seems to be right "thickness" where the bolt goes. Am I missing something or is it suppose to "float". ---- Automatic TH 400 ------ Thanks JIM.
All the T400 trans I've had apart were like that. As a matter of fact, I think mine had the bolt that only had threads so far and the rest of it was unthreaded. The filter doesn't snug up to the valve body like a T350 does. I have used 2 O-rings on the tube that goes up into the body to make a good, tight seal so it won't suck air or get loose.
Thanks knucklebusted, YES --- The one bolt That is in there is threaded half way, then the rest of the shaft is smooth, then the bolt head. -- I thought I lost a spacer or the previous owner forgot to put parts back in. So you ARE saying it just kind of "floats" / rides up n down with the trans fluid. In my 1970 buick manual --I didn't find anything that mentions that it floats --just to torque it down to 10 ft. lbs. ---- By the meaning of tube , I take it you mean the plastic tube from the filter up into the trans, body . Thanks JIM
That trans bolt is a special with large dia to act as a spacer. Yes, it lets the filter flop around a bit. Bruce Roe
As an avid T-400 builder, and an ASE Master tech... the T-400's always had a "loose" fitting filter. Also, if you have an older T-400 that uses the old "Can" style filter, you can use a newer filter by using the plastic extension used in normal t-400's and the newer filter.... Most of the time IF you can find the older filters they are about $30.... plus a pan gasket for about a buck... you can buy a new kit for about $15...make sure you use NO silicone... put the gasket on dry and torque to 100 inch lbs and you'll never leak again!
I always convert to the newer filter. But it needs the newer (deeper) pan, and drill/tap the valve body for the bolt. Bruce Roe
I have used either a spring on the bolt or a nut on the bolt (nut on top side of filter) to keep it in place.
