I've had an FD with a LS1 4L60E conversion for a few years now, & I followed instructions from the old V8 RX7 site to add a resistor in the generator circuit as GM used the resistance of a dash light bulb for the Gen circuit. Granny's site says that later LS1's do not need this resistor, so I queried the members about it & I was reassured that indeed I needed that resistor. NOT TRUE !! When the engine was warm the solenoid would only click,when I tried to start it, so I thought I needed a new solenoid. Bought one, installed it & a few days later same thing! So I started monitoring voltage digitally when driving, to my surprise 11.8V !!!! It would only ever get to 12.3 only after engine crank. But what really made me clue into it was last year (car is in storage over winter) the 4L60E packed it in, cost me $2,000 to repair. This year I drove it 2 mths then all of a sudden 3rd & 4th gear would only slip. I pulled the tranny out again & the shop did the warranty work on it but then they found out my running voltage and told me that a step solenoid in the tranny runs on increments of .1V to provide pressure to the clutch packs. Guess why 3rd & 4th blew out!! I took the resistor out today and guess what? 13.4 volts!!!! My LS1 / 4L60E package came out of a 2002 Camaro. So consider this a warning for you guys doing this swap.

 

thanks for the heads up...



I'm not knocking you putting an LS1 into an FD... hell, my vette has one in it..good engine, tough as hell...... but for the love of jebus man, why put an automatic tranny in a sports car, let alone an FD?

 

Jebus ! LOL Just trying to help out... I hear ya man! BUT I'm 58 yrs old, I love the car, it's a go cart rocket, my daily driver & I've been shifting for way too many years to enjoy it in traffic every day. & besides It's MY car right? BTW if that's your charcoal 7 it's a beauty! I love the name.
