4l60e transmission pump going out
i have a 2000 silverado swb put an ls1 out of a 2004 vette fully bolt on cam 4l60e tranny with a 2700-3000 Circle D stall, shift kit ,corvette servo ,blue clutches 390 gears and eaton posi unit! ever since i put that ls1 motor my transmission pump keeps going out! does anyone know what could be the problem! thanks
converter not staying all the way in the pump ive heard that some Circle D stalls need to be shimmed and if yours is burning pumps that often id most likely check that...Originally Posted by jhinojosa

i called chris from circle d he told me to shim it nomore than an 1/8 but it still keeps burning it dont if i should go with a billet one
Torque Converter InstalationsThanks goes out to Vince at FLT for this write up
This topic of discussion seems to be one that I constantly get asked. With the help of Terry of Precision Industries aka Vig converters I wanted to post this. This text is what comes with all converters that they have built in the past few weeks. The idea for me here was really about converter spacing. The problem we face as builders is guy's do not get the converter in all the way and break the pump and converter on the install. Or do not get the spacing correct and damage a pump and converter down the road. I was basically posting the directions that PI is now supplying. I feel that it is good stuff and wanted to share with all of you. Here it is.
Torque Converter Installation
1. Using a lift or jack stands raise car off the ground far enough to be able to slide transmission out from under the vehicle.
2. After the vehicle is raised, drain the transmission fluid into a drain pan by removing the pan bolts from the rear half of the pan then slowly loosen the remaining bolts to allow pan to tilt down towards the ground allowing the fluid to drain into the drain pan.
3. Remove the battery cable, starter (if necessary), driveshaft, torque converter bolts, exhaust (if
necessary), cross member and all of the transmission bolts except for one near the dowel pin.
4. Raise the transmission up slightly by placing a suitable transmission jack under the transmission.
5. Remove the last bellhousing bolt and remove the transmission.
6. Check the flexplate for cracks and chipped teeth on the ring gear. Take the new torque converter and hold it against the flexplate to see if the application is correct by checking that the pilot size and bolt circle are correct.
7. Add a quart of new transmission fluid to the torque converter. Using the aid of a helper, stand the transmission on the tail shaft and carefully install the torque converter onto the transmission. Spin the torque converter and listen for 3 distinct clicks as it drops into the transmission. The following are measurements you can make to insure the torque converter is all the way in the transmission:
GM-TH350, Powerglide=1.125" from bellhousing to the converter pads.
GM TH400 = 1.187" from bellhousing to converter pads.
GM 700 R4, 4L60E, 200-4R = 1.125" from bellhousing to converter pads.
GM 4L80E = 1.030" from bellhousing to converter pads.
Distance may vary +/- .050".
8. Remove any debris in the crankshaft pilot hole and lubricate. Clean and lubricate the dowel pins. Check to see that dowel pins will be in the transmission bellhousing by more than .250".
9. Mount transmission to the back of the engine block making sure the bellhousing fits squarely against the block. If it does not, find out why! Is there something between the bellhousing and block or has the torque converter slipped out of the transmission? DO NOT PULL UP THE BELLHOUSING TO THE BLOCK USING THE BELLHOUSING BOLTS!!!!
10.After the transmission bellhousing bolts are tightened, check to see if the torque converter will turn by hand. Push the torque converter back into the transmission as far as it will go. Using feeler gauges or calipers measure the gap between the flexplate converter mounting pad and the torque converter mounting pad. If gap distance is between .060" and .187" it is OK to bolt up the torque converter. If the gap is greater than .187" install a .060" flat washer between the torque converter and flexplate.
11. Finish installing the cross member, exhaust, driveshaft, etc. Add 5 quarts of good quality transmission fluid. Start the engine and immediately add 2 more quarts. Check the fluid and finish filling the transmission to proper level.
fuddle torque converters are the worse, they have to be SHIMMED, at lease the 2 i have experienced:
doing this will save your tranny fluid pump
another note if you dont have a deep pan GET ONE!!!also a good tranny cooler i run 2 in parallel to each other, i keep my temps down below 150 on the hottest day
thanks for the help
