Was reading a post by Badnewz about his gear vendors/TH400 combo.Is the 4l80e as strong as the gear vendors and what are pro;s and cons of each.Badnewz please chime in,I just didn't want to hijack.Just an interesting comparison:biggrin:

.The gear vendors unit does produce an overdrive ratio at a lower power loss than the 4l80e.This is because the Gear Vendors unit overdrives the output shaft and the 4l80e overdrive unit must overdrive the forward and direct drums,and both gearsets because it is located in the front of the transmission.
SS/GN are you contemplating a 4L80E install on a turbo Buick?
Norbs I dont believe it is that low but it is definately less than a 4l80e.I prefer the 4l80e because of its compact size in comparison to the gear vendors.You definately save money on the custom driveshaft with the Gear vendors because of the length.LOL.In the cost dept,if you already have a good th400 and converter and get a good deal on the gv unit it may be a better bet.What is the going price on the gv od unit?
Curious....
I read some info on the removal of many lbs of wt out of a 400.
Are any of the weight reduction mods for the 400, applicable to an 80E??
Not sure if this has been posted but here it goes. 4L80 gets my vote. The GV when used with a loose converter seems to slip the converter more in the OD position giving up the RPM to slippage at cruise you were trying to reduce. Quite honestly just feels sloppy. With the 80 lock the converter down and none of the slippage to deal with.
