Electronic control box for E transmissions

[HAULIN IT]

Chris, It's good to know what is breaking,Thanks. I've seen/heard inputs & outputs (they are the ugly ones it appears). We were told back in '95 when we put the 700 in behind the stock Olds...."It'll never live", it did for several years of daily use & occasional beating. Then when I put it back together a few years ago planning to race it some..."It'll NEVER live". 77 passes & 15,000 or so miles.... I really don't think about much anymore I know someday it's likely going to break something, anything beat on long enough gives up & when it was really never designed to, your odds are worse. What is funny to me is, my transmission friend is changing the drum on the input shaft (twisting the spine in the drum) in stock vehicle allot. (that's how I get the free, S-10 torque converters, the warranty companies give him a new one when he does the drum job & I get the old one) He has it figured which years of drums to avoid based on what year vehicles started having that problem. Did your brother's input snap or strip the drum? I'm assuming the pump went out with it that time also, what else, do you know?
 Vile & Tusk, That's what I've been pondering "Who's do you want?" I really don't have good faith in TCI components, but have never used any electrical items from them. That's why I was hoping to find a few guys who have one & are using them, Thanks. Lorne

I've never used TCI's standalone computers but I've never heard anything bad about them either. I build all my own transmissions and I had planned on building a 4L80E but the 6L80 is a better choice and will fall into my hands sooner or later so I'll wait til then to investigate a good standalone that I can vouch for it's quality.

Here is a list in order of occurance after the turbo.  ( he is sitting right here.. )
#1)burnt the clutches up
#2)snapped the input shaft in two
#3)shattered the pump.

[VileZambonie]

Clutch burn up = either too much clutch pack clearance or lack of holding pressure. Coulda been his pump causing all of the problems since it grenaded. Was he running a 13 vane hardened pump? They make a lot of must have upgrades for the 700r4/4L60. Input shaft & drum, reaction sunshell, pump, servo, clutches & band, reprogramming kits by transgo are pretty good. Those are a few items I would go aftermarket during a heavy duty overhaul.

I know you asked about electronic controllers, but this is just another choice.  I believe TransGo makes a full manual shift kit for the 80E trans.  Somebody suggested it to me when I was considering using one in a swap project.

#1 happened on a FLT Level2 trans, it lasted about 9 months of weekend drag racing behind 560 torque. (stock pump)

#2 happened on a FLT Level4 trans, it had 13 vane pump,  FLT doesn't put a hardened shaft in it.  He wasn't racing it during this time.(700 torque and 6.0L)

#3 happened on a FLT Level4 trans (same as above) but the cause was an unshimmmed torque converter..


BTW, all of these were dyno'd before sending them out.
