Does anyone have experience converter a 4l80E to full manual control,
Ive had a new 4l80e auto transmission sitting on a shelf in its factory packaging in my shop for a few years, that I want to convert to full manual control as it will make installing it in a car far less difficult than wiring in an expensive computer control module. now you may or may not agree but I think a full manual control shift kit is the most effective route to take in installing a 4l80E transmission in a performance application.
there are few CHEAP options once you decide to boost performance a great deal over the original cars power level, every change can and frequently will require other changes.
youll want a separate transmission fluid cooler,
youll need to change transmission mounts and the drive shaft in most transmission swaps
the lure of the top gear over drive ratio is un-deniable.
the TH350 is just not that strong, the more structurally sound or stronger TH400 ,
does not have the over drive ratio,
the 200r4 and 700r4 and 4l60e do, have the over drive top gear ratio,
but all three are not designed to handle significant impact and torque loads
in any G.M. transmission that your likely to find at a semi reasonable price,
in a salvage yard, that leaves the 4l80E ,
but the 4l80e controller costs about $500-$900 ,
and the performance torque converters can get rather expensive.
the partial solution is converting the stock 4l80e to full manual control,
thus avoiding the expensive programmable controller,(theres always compromises made)
and installing a performance shift kit. yes the 4l80e is physically larger and heavier , thats to be expected in a much stronger transmission design, but it can be swapped into many applications if your willing to modify or fabricate custom parts as required.
there are kits available too allow full manual control on a 4l80e thus eliminating the high cost of an electronic controller being required, and from what Ive heard they work rather well if properly installed, there are also now several lower cost programmable controllers
NOW that I own a 4l80e for my corvette project car and would prefer to have it converted too full manual control,using a floor shifter, for several reasons ,I would like to get some feed back, as many of you know the transmission can be converted to use a set of manual switches or run with a programmable controller.
If you have a 4l80e thats converted to full manual control ID like to know who you might suggest does the best conversion work, and what shifter and mount brackets your using?
yes I can do the work myself , but I've only rebuilt a a couple muncies, and a couple TH400 transmissions and thus I'd rather not get into working on a transmission I'm not absolutely comfortable modifying because I intend to put this behind about 700ft lbs of torque and obviously that will cause issues if the transmissions not 100% correct.
according to G.M. in stock condition
The 4L80E has gear ratios of 2.48:1 (First), 1.48:1 (Second), 1.00:1 (Third), 0.75:1 (Fourth), and 2.07:1 (Reverse). When the 4L80E was introduced, torque capacity was vehicles up to 8,000 pounds and engines producing up to 440 lb-ft of torque

The 4l80e transmission weighs 40 lbs more than a 700r4. 134 lbs vs 1741lbs , that's real world numbers. and the difference is in far stronger parts, properly build 1200hp is easily handled

Just RTV on trans?
The factory used some kind of sealant on the 4L80E, whats the difference on a Turbo 400? About the only thing I haven’t tried yet, tighten the 13 bolts to feel. The shop wants $286 to swap gaskets and refill, I think that is crazy. Anybody ever just use RTV and no gasket?
