my shortcut on the pump was just slip it on the converter and tighten up the pump, the remove the converter and bolt the housing on the trans, also did you do the oil drain back mod to the pump seal area , and always use the new style front pump seal from ford , Better and take more heat, A4Ld takes the same pump seal as the C-3, also more info, if your going to put this in your V-6 pinto like I am use the 4.0 A4LD and use the 2.9 converter , 4.0 is low stall , 2.9 high stall, if you buy one it will only come a few ways ,OEM, 2.3 A4Ld Ranger .mustang and some Turbo T-Birds, 2.8 2.9 and 4.0 have the same bolt patern, 3.0 is all by it self , they are other versions of the trans , but you need a computor to make them work, as for the first one I cooked was in a 86 ranger 2.3 , towed in overdrive, after that bigger coolers and toed in drive and even have manual lock up switch, truck has 250K no problems wifes bronco II trans craped out at almost 400K, it a good transmission if you know what you can and should not do with it, one is change oil in it every 15K, works for me,
