I did very little searching since I'm in a bit of a hurry, {need to get parts ordered} but found no results for 'isolator valve'.
I'm trying to get all the parts together to rebuild my 4l60e in my 96 trans am this weekend. I have a TCI #378950 rebuild kit. A short tech info sheet that came with the TCI kit mentions a Sonnax kit and reamer available that includes an isolator valve, sleeve and regulator valve. It is intended to correct PWM boost and actuator feed oil loss and correct for slip code on 93-97 units.
Since I'm going to be using a 3000+ stall converter with an OBD1 {conversion} PCM, will this kit eliminate the problems that are common with using a high stall speed converter with OBD1? If so, has anyone got a part # or link to where I can order it?
Also my rebuild kit does not include vanes for the pump. I have only built non-electronic trannys and not familiar with the 4l60e. Shouldn't I be replacing these vanes while I'm in there?
Do I need to order a 0.490 boost valve? Beast sun shell?
This car sees daily driving around town with little highway use and 20+ 1/4 mile runs yearly. Dyno #'s are around 280 rwhp/ 305 rwtq now but a cam, heads and n2o will be added soon so I'd like to build the tranny pretty strong now although the $'s are getting low. I can come up with $300 or so more.
Are there any other parts I need to get ordered?
TIA,
Mike

Thanks. I will likely need to. I have never built an overdrive automatic {only TH350-400, 727, c6 ect.}so I'm sure I'll have some questions.
Here is a list of what I have so far:
TCI super pro overhaul kit #-378950, new TCI street fighter 10" 3000 stall converter w/ 12" lock-up clutch, SPX Filtran beast sun shell, pistons #'s 24205273, 24205272 and 24200290 with molded seals {not included in overhaul kit}, all bushings from GM, all Torrington style bearings from GM, all thrust washers from GM, pump vane kit {10 vane}, Sonnax 0.490 reverse boost valve, Trans-go TCC apply valve upgrade kit #T74165E, 10"x10" trans cooler mounted in front of AC condenser/ 8"x8" cooler mounted in front of left front tire with pusher fan on top, Energy Suspension trans mount and TA bushing.
I plan to start re-assembling it Friday morning after I get off work {I work 11pm-7am shift}. I'm going to Macco transmission supply in Memphis in the morning to pick up the Transgo kit, bushing installer set and seal protectors so if I need to get anything else I need to get it then if possible.
I don't have solid seal installer/ re-sizer tools so I took the turbine shaft to a local tranny shop to get them put on yesterday. I made a piston return spring compressor and used a valve spring compressor chained to bolts in the case to get that apart. worked pretty well.
