Tranny replacement Advice

[leadtrombone]

Reading through another part of the site i came accroll this comment...

Do not know on the stall of the converter, it may be lower actually due to the added weight. For a similar "K" factor (how they measure slip) if you have more weight the stall speed goes up slightly. The common swap in the day was a 2200 RPM S-10 4.3L converter, or a 'vette converter both of which are 2200 stall. Naturally, you lose some mpg with that but less due to the lock up at highway speeds. The gears are nice if you tow, and if you tow a lot the sacrifice in cruise RPM may be worth it to you just so you have extra towing ability. Another thing is that with some mods you can probably tow in OD, which would gain some mpg.

I ask only cause i am getting ready to replace my tranny with a 4l60e from a Blazer/Jimmy. Now this being in mind, will the torque converter from that blazer be a different one than in the Safari/Astro, and if so would the higher stall speed actually be better or worse..??

Any thoughts on this.

Any other tips, trick, or watchouts when doing this job??

Thanks guys.

My guess is both convertors would be the same stall. And this is good as my advice is stick to what GM originally installed.

I don't have the specific answer for you, but some advice, take it for what it for what is worth.
wait for more responses and do some more research online. The vehicle weight and the gear ratio on the rear end is going to play heavily into the stall rpm on the torque converter. This is one of those things you don't want to get wrong...evenly marginally. It may "work" more or less and will frustrate you every time you drive it, or it will be a major fail.
