Trutech Performance Transmission

Neal B: Kansas: Customer Comment Engine Description

Engine: ATI-Procharger D series, 12 lbs boost, intercooled. LS-1 Iron block 408 fully blueprinted, all forged, cam is hydraulic roller extreme energy series 218 degree 0.580 lift. Heads are only pocket ported stock valve size. It is speed density tuned with EFILive, 65lb injectors, rpm limited to 5400 due to the massive hp and torque numbers the engine is capable of. I have not dynoed the engine---my knowledge is much greater in engines than trans., however,----the engine will dyno between 650 and 700 hp at 6000 rpm and 600 to 650 ft-lb torque at 5200 rpm. This is conservatively rated according to ATI ProCharger

Neal Comments:
"Shifting is great, solid and not harsh, quick but not bone shattering. Upshifts, downshifts are at the right time and feel great." "the entire trans. seems to operate like it did when it was new only much more decisively. Thanks sincerely for all your help."

My buggy weighs about ~4000 lbs and I run a built supercharged 4.3L V6 with about 350-400hp that I redline at 6000rpm. I typically will shift the tranny about 100-150 times in a 30-45 minute lap. Most is 2-3 or 3-2 shifts.

What I race is called endurance rock racing and I race in two series, RCROCS Race Series and Ultra4 East. The defining characteristic of these series is that all vehicles must be capable of 4-wheel drive. Beyond that, the class is unlimited, which means these vehicles come in all shapes and sizes and are capable of speeds of over 100 MPH and still contain gear ratios as low as 100 to 1 for technical rock crawling.
This coming year I'll start by competing in the big "King of the Hammer's" race in California. I'll follow it up with the Ultra4 East series, RCRocs Race Series and some local rock racing and rock crawling races.
The tranny will definately get a work out this coming year. Most races are 3-4 hours long but the King of the Hammers race will likely be 8 hours plus depending how we do.

Hey, Jeff,

I had my transmission in for about two months now and it really works good. I'm very happy and would recommend you to any one looking for a built 700r4. It went in perfectly, although I had to modify the cross member to fit the deeper pan but that was a piece of cake and turned out nice. Here is a picture of my truck its still a little ruff around the edges but its a work in progress. It has a 383 in it that I built last year and with the solid transmission should be able to get on the dyno and see what it puts out.

Jeremy is a young man of 26 years, and this is Jeremy first time to do a engine rebuild.


Thanks again
Jeremy Petersen

I can warmly recommend TruTechTrans as a quality parts source to anyone planning to rebuild GM 4L60E/4L65E/4L70E transmission. This was my 3rd time working on automatic transmission and I needed advise and hand holding. Jeff did not mind me contacting him several times during the process. He carefully explained best practices and procedures for a successful rebuild. He also covered some common GM rebuild pitfalls. After 4000+ miles transmission works flawlessly. Shifts feel is crisp and transmission noise very low.

Thumbs up TruTech.
