Hey guys...any Tranny experts out there???

I need to replace my 1-2 shift solenoid in my tranny...from the info I am getting,
Sounds like I have to drop the tranny...Is this true?? and if so..what do you recommend on other things that should (or could) be replaced also...

Of course ALL wearable parts is probably the most sensible answer, But I am (will)
be working with minimal cash on hand...
Thanks for any and all input...

in General Information.
Remove the park/neutral position switch. Refer to PNP Switch Replacement
Install the J 28467-360
Raise the vehicle. Support the vehicle. Refer to Vehicle Lifting and Jacking in General Information.
Remove the left front tire and wheel assembly. Refer to Wheel Removal in Suspension.
Remove the inner splash shield.
Remove the tie rod end from the knuckle assembly. Refer to Strut Assembly in Suspension.

Remove the pinch bolt from the steering gear intermediate shaft. Refer to Intermediate Steering Shaft in Suspension.

Caution
Failure to disconnect the intermediate shaft from the rack and pinion steering gear stub shaft can result in damage to the steering gear or to the intermediate shaft. This damage may cause loss of steering control, which could result in an accident and possible personal injury.


Remove the intermediate shaft from the steering gear. Refer to Intermediate Steering Shaft in Suspension.
Position a transmission jack under the transmission oil pan. Raise the jack until lit supports the transmission.
Remove the three frame-to-body bolts on the left side.

Install the new side cover bolts. Tighten
Tighten the side cover bolts to 11 N·m (98 lb in).


Notice
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.


Install the oil cooler pipes to the transmission. Refer to Automatic Transmission Oil Cooler Pipes Replacement

Hey thanks..Al...this is exactly why I love this club..

By the way...is there a way to electrically diagnose the tranny components...seeing that I am there already...good common sense tells me to do this one time only..

I have heard that maybe placing the internal valve may not be a bad idea also..

Any take on this...

Thanks again.....

How did you determine the 1-2 solenoid was bad?

Pulled the codes...had a 36 & 56..36= trans shift control 56= quad driver. went to Autozone for the print out...describes areas that could be affected...deduced that it was 1-2 solenoid by process of elimination.

A realtime scan would show when it'* actually trying to shift while driving. Comparing what the scantool says to what you observe through the seat of your pants and on the Tach can be invaluable. Do this during automatic shifting and manual shifting. That'* the best way to be sure.

I agree...I am checking the bonne in on friday...I'll post the results..!!

would anyone recomend replacing the shift selenoids as a way to pro-long the trans life? Cause if its able to be done without dropping the transmission I'll do it!

I wouldn't unless you were having a shift problem. It'* not fun, and won't buy you anything unless they're bad.

I have a TCC code 1864; 2 to 3 shift sol stuck on 0756; 2 to 3 sol 0758 and 1 to 2 0753. Feels like trying to start in OD. Have to shift 1;2;3 to get it going. Cruise not working either. Plan on replacing TCC; 1 to 2; 2 to 3. What about 3 to 4? should I replace that also since we are in it?
