First off, throw away that pan, OK?

Second, do you by any chance rev this engine over @5500 on a regular basis? Do you have the Hi Rev Release Springs from the TransGo kit installed? Do you have the TransGo Hi Rev Pump Ring Kit installed?

On top of this you have to make sure that the bushing in the back of the pump stator isn't worn, allowing the Input Drum to move off center, hitting the inside of the Stator and wiping out the sealing ring surfaces creating a leak.

Also, when this is apart have the 4L60E 3-4 pack installed or modify that with the use of stock steels and extra clutches depending on power. While there, have the 4L60E Sprag Assy. installed too.

Oh, yea, toss the cooler along with the converter so you don't contaminate the new tranny with leftovers. Get a TruCool and bypass the radiator.

 

toss the pan?....?
i do not have the high rev pump springs installed

i did install an assortment of springs and different vavles while following the directions provide from trans-go

the tranny is a 92 i forgot to mention...i dont know if there is a significant difference pertaining to the info you gave me?

where do you get a truCool?

Yes, toss the pan. You MUST keep the filter covered at all times with oil and this means that the filter must be very close to the bottom of the pan. Those pans don't allow this. When you have the tranny done, go with the 4L60E 3/4 pack along with the Hi Rev Release Sprigs that came with the TransGo Kit. Install the Hi Rev Pump Ring Kit too. You can get a B&M super cooler as it IS the TruCool, just under their name.

 

i dont even know if my tranny is gone i was able to drive home with it in "d" i was told that if the car would shudder every time it came up into the stall that more than likely my converter was going out..? i'm like ..ok,
thing is ,is that i dont wanna stick an 800$ dollar P/I converter in a blown tranny, i might just go with reliablity and swap it for TH350 OR 400..i dunno i have and extra 700 that also needs a rebuild and i allready have a TCI master rebuild kit in the garge and clutch spring compressor and all , even a video on how to do it, i've never messed with trannys before, other than shift kits... so i'm not optimistic,
