As my first real tech post let me post this warning: If your LC is S/C'd or your planning a Turbo be advised:
Issue: My opinion: The A343 tranny can not sustain the increased torque during the 1-2nd gear shift on an S/C'd Cruiser. The 'slide bump" is the term used.
Symptoms: My suspicions were confrimed via www.gadgetonline.com. The Foreunners that have the same tranny and are S/C'd from TRD have this problem. Under heavy acceleration the 2nd gear shift "hits HARD...causing havoc on the tranny and wearing out the clutch plates due to the increased power.
My LC was S/C'd with 41,000 miles . My 95' currently has 80,000 miles with 35's.
Under heavy throttle 2nd gear hits hard and jerks the truck.
Possible reason: Big tires contribited along with the S/C?? I dont believe larger tires were the reason. Forerunners had this problem long before the 80 series S/C was out. Forerunners were NOT running 35" tires. Besides i regeared to 4:56's and have the Speedo calibration unit.
The CAUSE: The valve body MUST be modified to sustain the increased power. Unfortunately, Slee does not have the Valve body fix for the A343 at this time. Luckily I have found a shop in Jersey that does all the work for Forerunners. I called them and they told me" oh yeah, we know all about that problem, send it in" Anyhow be advised, if you plan on a Turbo or an S/C GET the VALVE Body modification. Obviously TRD screwed this one up with POOR R&D. We were all guinea pigs when it came out . Ever wonder why TRD does NOT have an S/C anymore for the 100 series???........
