jdelhorbe Posted September 24, 2005 Report Share Posted September 24, 2005 I just replaced the A & B shift solenoids in my 1993 STS (only 44,000 miles on it). The trans would not shift from 3rd to 4th, then the 2nd to 3rd shift broke. It works AOK now. The solenoid kit cost $73 and the pan gasket $43 !!!. I got the parts from a GM dealer. The solenoid kit had a note from GM to dealers. It stated "All Transaxles assembled prior to 04 1996 require replacement of the A&B solenoids, please refer to GM corporate Bulletin 77-71-73 dated december 1997". Does anyone know if this was a warrenty recall fixed for free by GM. IF so can I get my money refunded from GM. Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted September 24, 2005 Report Share Posted September 24, 2005 Looks like it reads, there are newer shift solenoids, and if you have to service the transmission, use the new ones: Bulletin No.: 77-71-73 A/T - Revised Serviceability of 1-2/2-3 Shift Solenoids Date: January, 1998 INFORMATION Subject: Service Availability of 1-2 and 2-3 Shift Solenoids Models: 1993 Cadillac Allante 1993-98 Cadillac Eldorado, Seville 1994-98 Cadillac Concours 1996-98 Cadillac DeVille 1997-98 Cadillac d'Elegance 1995-98 Oldsmobile Aurora with HYDRA-MATIC 4T80-E Transaxle (RPO MH1) and with 4.0L, 4.6L Engine (VINs C, Y, 9 - RPOs L47, LD8, L37) During the 1996 Model Year, transaxle Julian date 047, a new 1-2, 2-3 shift solenoid assembly, and a pressure control solenoid valve fluid filter retainer, were implemented on the 4T80-E transaxle. All transaxles with a Julian date prior to 1996, 047 must be serviced with a service kit - 1-2/2-3 shift solenoid valves, which is available at GMSPO.

All components in this kit must be used when servicing these transaxles. 1996 transaxles with a Julian date after 047, and 1997 through 1998 transaxles, should be serviced with individual components Bruce 2023 Cadillac CT4-V Blackwing Follow me on: Twitter Instagram Youtube Link to comment Share on other sites More sharing options...

Scotty Posted September 24, 2005 Report Share Posted September 24, 2005 OneSweet, you have a different transmission than jdelhorbe, your tranny does not have the solenoid issues. Are you having trouble with your tranny? Link to comment Share on other sites More sharing options...
