Ok obviously Will has been sleeping.
The ASG 4t60-e is easily as strong as the 4t65-e and stronger in a stock format. They rebuilt the chain for that reason. The upfront cost is higher than most but Domestic Performance doesn’t like to deceive like many of the other companies. Other companies charge a core charge and then when they receive your core they reduce its value (usually to 1/4 of its value) due to the fact it has been used. This is not unfair but you are usually not told this until later when its too late. The only Performance Transaxle with a real warranty is the ASG 4t60-e coming with a 3 year 36000 mile warranty. Other companies have to offer a 90-day warranty.
The final cost for a top built transaxles is going to be 3800- 4000.00 regardless. I currently offer Limited slips, performance shift modulators, torque converters, the works. I can also hook you up with a stick built to take on 450.hp.
None of these transaxle stick or even RWD conversions are hard but they can be expensive to have done correctly. I have a funny feeling we will have some hard knock cases of learning with trial and error in the next little while. I screen calls on a regular bases for our tranny tech and if you need help I am always glad to help. I am not going to give all our secrets but I will help as much as I can.
