90 with 4.10 Gears and AOD tranny
Meaby someone on here can help, originally wanted to swap a t5 into my 90 but had a hard time finding a legit WC t5, so I went ahead and installed 4.10 gears before i begin gathering parts to complete the swap. I didn't look much into the speedometer problem since I kind of knew it would just take a tooth to fix it, but turns out that late model fox body AODs and 4.10 gears don't mix well with speedometers. Wondering if anyone has found something that's worked well for them, i know the biggest tooth LMR carries is only a temporary fix.
Which brings me to my next question, if I install the tooth I've heard the teeth disintegrate, will it affect the tranny or just change the ATF?
