Re: 408 Hummer road test....Medford to LA
After careful consideration, went with a CK Performance(out of New York area) built 4L65e. Price was right...2600 for transmission, and 400 for converter (400 rpm higher stall), and 400 core charge. The FLT and Yank was 5000 bucks. CK also gives a 12 month warranty. He swears it won't break unless I start BAJA racing....I did not want to swap to a 4L80e unless this one breaks. I like the low first gear, and the lighter reciprocating weight of the 65e. It should arrive in a month or so. After the 4.56s and new trans are installed , I will do some youtube videos (0 to 60, 0-max speed) and some off road action. I am constantly pegging the stock tach which should break soon. With the stock 4.10s and 37 inch tires, it was easily pulling 100 mph in second gear....at 60 mph it was almost idling down the Autobahn. It is in the shop at Geiger Performance, Munich Germany, getting some new fuel injector connectors installed. I was getting a PO200 code and it was missing off and on. Hope to get it back next week and terrorize the locals....is next mission is to add LPG injection (autogas in Europe). The 8.33 a gallon gas is killing me.....
