============================I checked my check engine light and got the code p0741 welcome to the club – one of mine has had that code for a while -P0741 is caused by a worn seal – replacing the solenoid will NOT take care of the problem – if you don”t have emission testing – you could live with it forever and never fix it – I have noticed the transmission acting up lately the P0741 has nothing to do with this – sounds like you have more/bigger problems – I”ve heard this job is a pain in the butt …trans has to come out and be disassembled –
Cool thanks for your input I”m not 100% sure my trans is acting up or if I”m paranoid haha …. the worn seal you said .. do you know which one it would be?

Re: Tcc solenoid repair 2003 Deville … any tips or walk through ??The transmission input shaft and torque converter have seals that contain ported TCC engagement oil pressure – they wear and you need to replace the torque converter and input shaft seals.Transmission out of the car.Subscribe the car to www.alldatadiy.com – it”s the GM/Cadillac service manuals plus a lot more. TCC work is all there.When (not if) the actuator solenoid falls apart you get a P 1860 code. That can be repaired with about 8 hours of microsurgery through the transmission side cover. Tips and videos in Engines; Northstar and in Tech Tips.Google “cadillac forums 4t80e tcc solenoid replacement” or something close.

http://www.nadechworld.com/forum…on/149834-information-p0741-p1860-1998-a.htmlOops, it appears all the diagrams have been deleted. :noidea:P.S.I live with that code and if it where not for the MIL, I”d never know the seal was leaking. As Bass said, if you are feeling the trans acting up, it”s not related to this code.

Re: Tcc solenoid repair 2003 Deville … any tips or walk through ??I have this code also but never feel the car run or shift any different. Most members report a 2-3 hundred rpm rise on the highway and maybe a 1-2 mpg loss on the highway. I personally get 22-23 mpg with this code, not bad. My mechanic wants $1100 to do this job WITH the tranny already out of the car for other reasons. The consensus on here is a straight fix with new torque convertor will run you about $2000-$2300
Re: Tcc solenoid repair 2003 Deville … any tips or walk through ??
The 4T80E is a 4-speed auto with TCC in 4th. 3rd is the direct drive gear at 1.00:1. 4th is OD at 0.68:1. TCC “locks” the converter rotor and stator to remove the last bit of slip in 4th.Your base Deville should get about 26 – 29 mpg on the open highway, long run. We have members with base Devilles and Eldorados who can document 29 – 31 mpg on long highway runs in level country at speeds from 55 – 65. For our cars, drag costs mileage above 65 mph.The absolute egg-under-my-foot best I have ever done in the STS is 25.6 mpg NC/SC flat Interstate at 60 to 65…….. but I have the 3.71:1 final drive, so that costs mileage.The TCC engagement test is done on the open road, above 43 mph, fairly level cruise speed load. Maintain speed with your gas pedal foot. Touch the brake pedal with your left foot. If TCC is operating and was engaged you will see a 300 rpm rise as it drops out – the brake pedal/TCC switch also drops off Cruise if it was engaged. Release the brake pedal and TCC should re-engage, dropping engine rpm by about 300 rpm or so.In either a VIN 9 or VIN Y car, TCC is good for a 2 – 3 mpg increase and is an emissions item, so if it doesn”t work the car won”t meet federal emissions for either a registration or point of sale test.Here are the speed/rpm tables for our cars with TCC operating as designed.
