I already lost a front pump in my th400. I had about 30 miles on my rebuilt 455, and set myself up with a 3200 stall, b&m torque converter. I slotted the converter in the tranny and bolted it up to the flexplate. worked pretty well, till i lost third, then second, then first, and limped her home after only 30 or so miles on my brand new set up. so... i go through a friend of a friend, he puts in the new front pump, new clutches, bands, some springs, and new sprag. I was told to go ahead and get a new converter, because the old one probably had crap in it. So.. i get a TCI converter ordered this time, and i hear that you have to space the converter so far into the tranny. can anyone elaborate? the search says sorry no matches no matter what i put in. thanks.
get a coan convertor b&m and tci tend to be mass built garbage but you have to get atleast 2 clicks when droping in a convertor how bad was the gears and pump housing rebuilt convertors do have tighter tolerances and you might have to use a rubber mallet to get the splines to seat completely
This is from the TCI site: What type of clearance should I have between the torque converter and flexplate before pulling the converter forward and bolting it to flexplate? Answer: You should have 1/8" (.125") to 3/16" (.1875") between the torque converter and flexplate before pulling the converter forward and bolting it to flexplate. Is there an ideal way to measure the converter and transmission outside the car to make sure you should have the proper clearance between the converter and the flex plate before installation? Answer: Yes, you can use a straight edge, laying it across the face of the bell housing. (Engine side) Then with the converter installed in transmission, take a ruler and measure the distance from the straight edge down to the mounting pad of the converter. The measurement should be as follows: GM Turbo-Hydramatic 4L60 1 1/8" from Bell housing to Pads GM Turbo-Hydramatic 4L60E 1 1/8" from Bell housing to Pads GM Turbo-Hydramatic 4L80E 1 1/8" from Bell housing to Pads GM Turbo-Hydramatic 350 1 1/8" from Bell housing to Pads GM Turbo-Hydramatic 400 1 3/16" from Bell housing to Pads GM Powerglide 1 1/8" from Bell housing to Pads Ford C-6 1 1/8" from Bell housing to Pads Ford C-4 1 1/8" from Bell housing to Pads Ford AOD & AODE 1 1/8" from Bell housing to Pads Chrysler Torqueflite 727 1 " from Bell housing to Ring gear (NOT PADS) Note: Distance may vary either way .050". If there is too much clearance, you need to use washers on the converter to flexplate bolts. If the converter is pulled out of the trans too much, the converter will not engage the pump fully leading to damage. Just measure it.
