HighClass SS

Im having the same issue starts at 60 or the jus get to where at 90 feels like ima lose something. So I did front and rear driveshaft u-joints and had both balanced. Well never felt so solid but this vibration is still here. Ive been told that the trans is going.It was only $300 with labor so not bad if you dont wanna get dirty. Ima go to the D/S an get a second opinion.

Went up against a 2006 ISS 2WD. Well I held him till 60 because of AWD traction but the weight difference of +400Lbs or so can't be beat it in the long run.

I heard of a few guys cutting up the old one and flipping the brackets or something. Don't hold me to this jus heard of it.

the map retards the timing i believe. so it takes care of the knock.

Im proof the worst thing ever!!!!!!!!!!!! I just did mine and well now ima pay 2k for it literately.

My Diablo Sport has that option. Their not to bad on price $300 or so. Bonus they have a 87 octane program in the unit already.

on my to do list. looks right!

My good guy at the service counter but not at chevy anymore told me the same. he did it on a 5.3 and he said it drove in and never drove out flush took the trans right out. hes been a service provider from chevy to gmc to vw i been bringing all my vehicles since 16. its the stealership that i dont like. but he swears by you should drop the pan and filter change an adding on all vehicles. flush is to violent. should of called him first but damn coupons. and ya to the trans leak.

th thanks. i having trouble deciding. 1. rebuild stock $1400 or buy reman from GM +/-$ 2000 2. stage 2 hd kit with a 24 or 2500 stall $1900 3. i found a performance 4l65e at gm performance but i cant find any info on it for $2200 p# 19260380 what to do errrrrrrrrrr! and no jus had it flushed new ujoints and front left diff seal and rear tcase seal

Trans is going bad!

ThankSS

Well I checked the tranny level and its fnnn 3/4" over the hash mark. Called NTB they said bring it in. But the question remains what damage can happen by over filling it?

The only way to say this is the WINTER been hell on truck. I noticed both my tranny cooler lines were leaking, haven't replaced yet due to -20. But I had NTB due a flush and filter figuring I'll go back once a swapped the lines for a fill. Now up shifting has become a struggle it seems. It takes it about 300RPM or 5-10SECS up shift from any gear. When im at 40% under on throttle the truck shifts fine. codes are: P0116 Engine Coolant Temperature Circuit Range/Performance P0125 Insufficient Coolant Temperature for Closed Loop Fuel Control P0128 Coolant Thermostat (Coolant Temp Below Thermostat Regulating Temperature) P0131 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 1) P0132 O2 Sensor Circuit High Voltage (Bank 1 Sensor 1) P0420 Catalyst System Efficiency Below Threshold (Bank 1) P0430 Catalyst System Efficiency Below Threshold (Bank 2) O2 sensors need replacing? P0740 Torque Converter Clutch Circuit Malfuction P0741 Torque Converter Clutch Circuit Performance or Stuck Off p0740-1 are my tranny issues what do you think deal is? I am redoing both drive shafts u-joints and balance. Also a front driveside diff seal.This thursday.

I know! I need to invest a voltage meter, but my diablo sport might tell me real time info.I gotta check.

Just had the similar codes. replaced t/b on 1/17/14 havent had any issues. blow a hole in the t/b casting from a gear or wtf. right next to the sensor.
