Question about 1999 Isuzu Trooper
My 94 Trooper wont run in drive until the trans warms up. Its like it kicks out of low gear to high but if i start in low and manualy shift it works fine.I changed the filter and fluid but it didnt help. It has 220000 plus miles. Is this normal or is this a fixable problem? Could it be the modulator valve?(does this truck even have a mod. valve?)
Ok if this is the wrong solution then you would have to recreate this problem 5 times to show up on a scan tool i know i went out bout the scan tool them i found out about the creating the problem 5 times from internet before the scan tool recognized it
i did all the swap outs of the sensors and egr valve and when i found out about trans solonoid i was like why me rear wheel drive is much easier to work on than front wheel drive cause its on the side of the trans where you can get to it
front wheel you have to lower the trans
before anything i would invest or borrow a scan tool this will pop up codes for your vehicle and with trans they require recreate 5 times
in the morning when its cold do everything normal as you were to drive it with out low gear shifting just put into reverse if it bucks and dies then its trans selonoid
egr would make your vehicle run rough like it was choking its emmissions stuff
and what i described up top is normal for your year and milage

Its called trans solonoid 15 to 30 part there is usually 3 but have all solenoids in trans replaced automatics are the only vehicle that have these
this give bucking sensation
when warm you wont feel it but when cold u will
also it reeks havack on torque converter get it fixed quick or trans will be worth more than vehicle is to rebuild
also u will start loosing gas milage down to 8 gallons per mile
i know this i have a station wagon sitting outside with same problem but its front wheel drive and i dont have means to fix it right now

If you are talkin about the egr valve, than yes it does. It can also be called the EGR Modulator valve, so your Trooper does have that but its not the culprit to your problem. If it was your EGR modulator valve, when you gassed it, it would die on you. I would check on your input or output speed sensor or BCM.
