I believe I have a t18 in my 87 2wd f150 with the 302... it had the 4 speed granny low. My question is what all trannys can I use as a swap?...I love the set up of this tranny but its starting to grind something in it under load so going to buy a rebuild one. Looking at my options since I'm going to replace it. Also I just had a new clutch kit put on do any of the other trannys allow me to use the same bell housing? Kinda wanting to go to the 5 speed because of the high rpms going 70 open to any and all suggetions and comments Thanks
