The original stock tranny in the Blue '94 Z28 has finally given up. For a few years, it's been rev'ing as if a missed shift occurred if you were at WOT during the expected 3-4 shift. Now it won't shift out of 2nd. What did you guys opt to do? From a brief research here's what I know...

'94 A4's are the first yr for the 4L60E in the Fbody (93 had a 700R4) and the '95+ got an extra solenoid on their 4L60E. So it appears you can put a '94 - '97 LT1 4L60E in a '94 but you can't/shouldn't put a '94 4L60E in a '95-'97 LT1 because of the solenoid.
I can buy a complete 4L60E outright (no core) from Summit for anywhere from $1,300 - $1,700 depending upon manufacturer/rebuilder(Hughes, TCI, B&M, etc).
I can buy a Hughes 4L60E rebuild kit with HP parts for $390 but from what I've been told, the insides of a 4L60E are not for those with ADD

I've called a local Fbody Boneyard and left a message, trying to see if he has a recent 4L60E and the cost. That brings up a question. Other than the Torque converter, are the LT1 and LS1 4L60E's incompatible?

Have any of you had your 4L60E rebuilt to 'standard', ie: not HP? If so, what kind of cost and time turnaround did you experience?
Thanks!

 

Posted the next day...

Just bought the Level 1 Pro Street 4L60E (w/converter) from the Performabuilt site. Thanks for the tip!

==========================
Good news! Just got the tranny from Performabuilt!
Bad news! They didn't have my Torque Converter in stock at the time of shipment. But, it's on its way. If things would have gone perfectly (as if that ever happens with cars, hahaha) everything would be here today so I could put it all together. Ah well...
The box arrives...

Thanks for the reveiw and glad all went well for you.

 

With the HP you're making and the times you're running, just wondering why you didn't choose the Level 2 or 3 Performabuilt 4L60E? Also, I know all their 4L60E products are quality.

I've detuned and demodded the '94 since I decided to give that Z28 to my daughter so she didn't need the added capabilities.

 

I didn't check closely, I thought it was going into the 96 w/ the 383.
